The text-figure is the work of Miss Helen Z. Hunt.Eptesicus capensis angolensis, new subspeciesTYPE.-No. 85535, Amer. Mus. Nat. Hist.; e adult, skin and skull; from Chi-tau, Angola. Secured by the Vernay Angola Expedition, Mr. H. Lang, collector,orig. no. 620, August 5, 1925.The American Museum has a series of 18 from the type locality; there are twoskulls, also topotypical, in the Carnegie Museum, Pittsburgh. Records of E. capensisin Angola, possibly referring to this race are Caconda and Huilla2; Vila da Ponte.8The more southern records may possibly concern E. c. nkatiensis Roberts.GENERAL CHARACTERS.-A race of Eptesicus capensis with blackish wings andyellowish-brown body, the hairs above and below without dark bases.COLORATION.-Upperparts darker than tawny olive, the bases of the hairs paler.UnderpatsUightly grayer than cinnamon-buff. Wing membranes and ears black.ish, uropatagium:,,lightly paler.SK-mL.-Braincase considerably higher than rostrum; the latter broad andshort. vOccipital height more than 65 per cent of mastoid breadth in adults.DENTIrION.-Medial upper incisor (12) deeply bifid; I3 with small posteriorcusp, only about one-third shorter than J2. Ii-s placed in line with the margin oflower jaw. Other teeth about as in E. minutus.1 1912-, 'Color standards and nomenclature.'2 1900, Seabra, Jorn. Sci. Math. Phys.

Secured by the Phipps-Bradley Expedition, Mr. Lee S.Bradley, collector, orig. no. 676, February 10, 1933.This species is known only from the type specimen.GENERAL CHARACTERs.-A blackish brown, grizzled species of Mops; skull withhigh lambdoidal- crest. IUropatagium reaches to heel, wing membrane attached tolower third of tibia.CoLoRATIoN.-Upperparts near fuscous-black, shading into black on the head,grizzled with whitish hairs and tips; bases of hairs paler. Underparts dirty whitish.Wings darker than fuscous, as are the ears. Upper arms and legs pale.SKuuL.-Short and broad; supraoccipital region produced more than usual forMops, but sagittal crest poorly developed.DENTITION.-TJpper incisors closely approximated, separated from canines by agap. p2 minute, situated laterally to axis of tooth row; P4 and canine in contactmedially. M3 about half size of MI and M2, with a V-pattern.MEASUREMENTS.-Head and body, 75; tail, 41; forearm, 46.3; digit III,47.0 X 19.4 X 19.9 X 8.4. Skull: greatest length, 23.3; basilar length, 17.6;palatilar length, 8.2; zygomatic breadth, 14.5; interorbital breadth, 4.5; mastoidbreadth, 12.7; outside breadth across M2 - M', 9.7; maxillary alveoli, 9.1; crownsP4- M3, 7.0; width Ml, 2.9.Except for coloration, this species resembles the description of Mopsangolensis (Peters). A specimen from Chitau, agreeing in color withPeters' description,' collected by the Pulitzer Angola Expedition of theCarnegie Museum, has less extensive uropatagium and the wing mem-branes attach to the middle of the tibia. Cranially the occipital regionis much less produced.1 1870, Jorn. Sci. Math. Phys. Nat., Lisbon, (1) III, p. 124.19371 3
