Upper Cretaceous Mollusca from Southern California

One new genus and thirteen new species of Mollusca are described from the Upper Cretaceous fauna of the Santa Ana Mountains, southern California. New generic assignments based upon discovery and study of previously unobserved structural features are offered for a number of common and well-known Cretaceous molluscan species. Some genera hitherto unknown in the Upper Cretaceous of the Pacific Coast are recognized, and their affinities are discussed

The coral fauna of the Midway Eocene of Texas

The coral fauna of the Midway Eocene of Texas includes thirteen separate species and varieties. Only two of the species, each represented in a single locality by a single specimen, belong to the colonial types. The remaining eleven species, containing probably 95 per cent of the specimens, are all of solitary forms. Evidently the Texas Midway seas did not afford conditions favorable to the growth of reef-building corals

Kangaroo Rats. Observationson the Kansas species of perodipus

Citation: Popenoe, Charles Holcomb. Kangaroo Rats. Observationson the Kansas species of perodipus. Senior thesis, Kansas State Agricultural College, 1905.Morse Department of Special CollectionsIntroduction: During the fall of 1904 it became my task to travel to the town of Kinsley, Edwards Co. Kansas, in order to investigate the depredations of the kangaroo rats (Perodipus richardsoni) in the sand hills near the place. In the investigations which followed, a number of interesting facts were secured, which, added to some previous knowledge of the animal, gained largely through a trip or two in the western part of the state, in the interests of the college entomological museum, and to much information on the subject by Prof. D. E. Lantz, then Field agent for the Experiment Station of the Kansas State Agricultural College, gave me an impulse toward the following subject. The kangaroo rats are members of the sixth family of the Rodentia, the Heteromyidae. This family is most nearly related to the Geomyidae, or pocket gophers, on the one hand, and to the Zapodidae, by jumping mice, on the other. They are characterized outwardly by the possession of fur lined, outwardly opening, cheek pouches extending back to the shoulders, and by long hind legs and feet, adapted for jumping. The characteristic features of the skull and dentition are rootless molars, narrow incisors, mastoids enormously developed and appearing on top of the skull, tympanic bones greatly inflated and possessing a nontubular metal orifice. The Heteromyidae are divided into two subfamilies, the Dipodomyinae and the Heteromyinae. The Heteromyinae includes the pocket mice of the genera. Perognathus and Heteromys, having shorter hind legs, feet with naked soles, and less fully developed tympanic bones. The mice of this group or the pocket mice are less developed for jumping, as the hind legs are not so strong, the tails are shorter and the bodies heavier than in the next group

Transposed Hinge Structures in Lamellibranchs

In the course of study of a collection of Eocene fossils from Claiborne Bluff, Alabama, the senior author of this paper noticed two valves, one right and one left, of the lamellibranch Venericardia parva Lea, in which the dentition is partially transposed. Subsequently, the authors made an examination of more than five thousand lamellibranch valves, representing both recent and fossil shells, in search of further examples of hinge-transposition. We have found a total number of twenty-six valves exhibiting this variation. Study of these specimens has revealed some hitherto unreported facts regarding the principles of hinge-transposition. Therefore in this paper, we shall describe and discuss these specimens, and shall present such conclusions as seem justified by the data assembled. Citations to the literature are made by author, date, and page, referring to the list at the end of the paper

El problema de la variedad en la horticultura tropical

La pomología tropical, carece del respaldo extenso de investigación técnica y desarrollo que caracteriza a la horticultura en regiones más septentrionales. Los que trabajamos con frutas tropicales tenemos que satisfacernos con material que es, hablando en términos comparativos, todavía primitivo. Además, estamos empeñados en explorar nuevas regiones en sentido hortícola. Nuestra tarea es determinar qué clase de frutas se pueden, cultivar en estas regiones y cuál es la mejor forma de hacerlo

Importantes frutas tropicales

La ciencia de la pomología tropical, aunque todavía está de recibir toda la atención que se merece, ha avanzado mucho desde principios del siglo actual, especialmente en lo que se refiere a algunos de sus aspectos más fundamentales, y de los cuales se tratará brevemente en este estudio

Islam and the Body: Female Fattening among Arabs in Niger

Is there a specifically Islamic vision of the body? Given the nuanced nature of cultural understandings of the body and Islam's own variable expressions, this question is probably unanswerable, and indeed poorly phrased. Phrased another way, however, the question of the relationship between Islam and the body becomes more interesting: how do bodily practices in different Muslim societies articulate with different versions of lived Islam? My research among Arabs in remote northwestern Niger on the aesthetic of corpulent female bodies, and the practice of forcefeeding young girls to achieve it, speaks to this issue

Team Approach to Pesticide Applicator Training, Testing, and Recertification in Four Central Florida Counties

A regional team approach to pesticide training and certification improves clientele opportunities to comply with regulations and requires less time per agent to implement the program. Agents in central Florida identified pesticide licenses with high public demand and developed education opportunities for this group. Program success was measured by comparing exam results from clients taking exams immediately after pesticide training with the results from clients who took the exams without training. Attendees realized a 21% increase in passing percentage. Agents can stretch limited resources and expand quality programs by reaching across county lines in a regional team approach
