Phylogeny and Taxonomy of the Round-Eared Sengis or Elephant-Shrews, Genus Macroscelides (Mammalia, Afrotheria, Macroscelidea)

The round-eared sengis or elephant-shrews (genus Macroscelides) exhibit striking pelage variation throughout their ranges. Over ten taxonomic names have been proposed to describe this variation, but currently only two taxa are recognized (M. proboscideus proboscideus and M. p. flavicaudatus). Here, we review the taxonomic history of Macroscelides, and we use data on the geographic distribution, morphology, and mitochondrial DNA sequence to evaluate the current taxonomy. Our data support only two taxa that correspond to the currently recognized subspecies M. p. proboscideus and M. p. flavicaudatus. Mitochondrial haplotypes of these two taxa are reciprocally monophyletic with over 13% uncorrected sequence divergence between them. PCA analysis of 14 morphological characters (mostly cranial) grouped the two taxa into non-overlapping clusters, and body mass alone is a relatively reliable distinguishing character throughout much of Macroscelides range. Although fieldworkers were unable to find sympatric populations, the two taxa were found within 50 km of each other, and genetic analysis showed no evidence of gene flow. Based upon corroborating genetic data, morphological data, near sympatry with no evidence of gene flow, and differences in habitat use, we elevate these two forms to full species

Nova Terrae-Mariae Tabula

This image was produced from an original copy of the map held as part of the Baetjer collection. In the spring of 2017 the Venable LLP law firm generously donated to the Sheridan Libraries most of the maps, views and prints in the Baetjer Collection.1 map, hand colored, 29 x 38 cm. on sheet 40 x 49 cm., Scale: ca. 1:1,450,000

Nova Virginiae Tabula

Description from Mapping Maryland: "This map is the eighth derivation of John Smith's Virginia. It is a careful copy of the 1633 Hondius map on the same subject. Ogilby included this work in his "America".Description from "Maryland from the Willard Hackerman Map Collection", George Peabody Library Exhibit Oct. 9, 2018 - March 16, 2019: "John Ogilby, who once styled himself a "dancing master," left our Powhatan's council and the Susquahanna Indian in his late derivation of John Smith's map. By 1671 the Smith map had become outdated, but Ogilby compensated his design with figures of putti at work, trading and taking measurements. The cartouche showing an Indian with headdress and a llama is more commonly found on maps of South American regions."1 map, hand colored, 29 x 36 cm., Scale ca. 1:1,400,000

Nova Terrae-Mariae Tabula

Description from Mapping Maryland: "This is a second edition of what popularly is called the "Lord Baltimore Map," which first appeared in Father Andrew White's "A Relation of Maryland," a 1635 publication devised to entice colonists to the province. John Ogilby, a one-time "dancing-master," produced this map for his illustrated atlas, "America".Description from "Maryland from the Willard Hackerman Map Collection", George Peabody Library Exhibit Oct. 9, 2018 - March 16, 2019: "This delicately hand-colored map is the second edition of what is popularly called the "Lord Baltimore Map". It made its first appearance in the 1635 pamphlet "A Relation of Maryland". In this later edition, the Calvert coat-of-arms has supplanted the royal English arms. Additionally, the boundary line of Maryland has moved ever so slightly further north."1 map, hand colored, 29 x 37 cm., Scale: ca. 1:1,450,00
