NORTH AMERICAN FAUNA. 



SlailL — The skull of Yesijertilio fnsms haliamensis is mucli smaller 

 and more lightly built than that of typical f uscus (figs. 24 a and 25 r/). 

 The skull of a fully adult male measures: Occipito-nasal length, 16.5; 

 zygomatic breadth, 11; mandible, 12.6. In form it differs from that of 

 true fuscus in its narrower, deeper, more cylindric brain case and less 

 shari)ly 'peaked' occiput. 



Teeth. — The teeth, like the skull, are smaller than those of iva^ fuscus 

 (fig. 2Qh). In a fully adult male the upper tooth row (exclusive of 

 incisors) measures 6.4 mm.; the mandibular tooth row, 7.8 mm. In 

 form the teeth differ slightly from those of true fuscus in the greater 

 breadth of the inner (lingual) side of the first and second upper molars. 



Measurements. — See table, page 103. 



Specimens examined. — Total number 90, all from the tyx)e localitj^ 

 General remarl^s. — Vespertilio fuscus haliamensis needs no comparison 

 with typical fuscus or with V. fuscus cuhensis, from both of which it 

 differs widely in size. Its superficial resemblance to V. fuscus pro- 

 pinquus is closer. Unlike the latter, it has a very narrow muzzle.

Ti/2)e locality. — Cuba. 

 Geographic distribution. — Cuba. 



General characters. — Externally similar to Vespertilio fuscus mirado- 

 rensis, but slightly smaller in general size, and with much smaller ears. 

 Skull about as large as in true fuscus^ thus much smaller than in 

 miradorensis. 



Ears. — The ears are delicate and papery, like those of the other 

 southern races. They are smaller than in either fuscus x)roper or mira- 

 dorensis. In form they differ markedly from those of true fuscus in 

 their general narrowness, and especially in their more i)ointed tips. 

 The characters of the ears have already been described by Mr. Chaioman. 



Membranes. — In form the membranes do not differ from those of the 

 other subspecies. In texture they agree with the southern forms. 



Fur and color. — The fur is distributed exactly as in the other sub- 

 species. In color the specimens, after five years' immersion in alcohol, 

 are darker and redder, especially on the whole ventral surface, than any 

 others that I have seen. They even surpass V. fuscus miradorensis in 

 darkness and richness of color. 



Slxull. — The skull of Vespertilio fuscus cuhensis is about the size of that 

 of tvMQ fuscus or a little smaller, thus distinctly smaller than that of V. 

 fuscus miradorensis^ the form to which cuhensis bears the closest super- 

 ficial resemblance, and much larger than that of hahamensis., its nearest 

 geographical ally. In form the skull is similar to that of true fuscum
