﻿EUDERMA MACULATUM. 



47 



Type localiti/. — Kear Pira, Ventiira Ooanty, California (probably at 

 mouth of Oastac Oreek^). Type iu Americau Museum of i^atural His- 

 tory (No. f 11^) Skull now lost. 



GeograpliiG distribution. — Under ma maculatum is known from the type 

 locality only. 



General characters. — Size large 5 ears about three-fourths as long as 

 forearm; color blackish blotclied with white. 



Uars. — Ears very large (PI. I, fig. 11), fully three- fourths as long 

 as forearm, joined together across forehead by a low band of mem- 

 brane; anterior basal lobe continuous with keel which extends upward 

 from anterior base of tragus and fades into substance of ear at about 

 terminal part of lower fourth, beyond which it continues to tip as a 

 well-defined line; anterior border of ear nearly straight through lower 

 half, then gently convex to broadly rounded oft' tip; posterior border 

 slightly con»cave immediately below tip, then convex to base; posterior 

 basal lobe joined to base of tragus by a low band, below which a distinct 

 pocket is formed; back of this band a couspicuoua ridge extending 

 inward toward meatus; ear membrane marked by about fifteen trans- 

 verse ridges; anterior margin of ear sprinkled with whitish hairs. 



Tragus nearly straight on anterior border, convex on i)osterior border 

 except at i)osterior base, where it is straight for a distance of 2 mm. (the 

 resulting form strongly suggests a table knife with short blade). 



Membranes. — The membranes are broad and ample, the wing mem- 

 brane (PI. Ill, fig. 3) attached at base of toes, the interfemoral mem- 

 brane at base of terminal caudal vertebra. Free border of interfemoral 

 membrane apparently longer than calcar. 



Feet. — The feet are moderately large, a little less than half as long 

 as tibia. Toes sparsely sprinkled with short bristly hairs on dorsal 

 surface and armed with strong claws. Calcar indistinct in the dried 

 skin, but apparently short and without keel or terminal lobule. 



Fur and color. — The fur is full and soft, about 12 mm. in length on 

 middle of back. It extends on extreme base of ear, and on membranes 

 forms a very narrow border close to body. 



Back very dark sepia, almost black; occiput and fore part of neck 

 distinctly less dark; hairs on sides and on middle of back faintly annu- 

 lated with gray near tips ; i)atch at base of tail and on each shoulder 

 pure white; whole ventral surface of body white, the blackish bases of 

 the hairs showing through irregularly; fur everywhere blackish at 

 base; ears and membranes light brown. 



Skull and teeth. — As the skull of Eudcrma maculatum is lost, I quote 

 the descriptions published by Dr. J. A. Allen and Dr. Harrison Allen. 

 The former writes : 



Sicull and dentition. — Basilar length, 16.5 mm. (0.65 in.) ; total length, 19 mm. (0.75 

 in.); zygomatic width, 10.9 mm. (0.43 in.); height, 7.6 mm. (0.30 in.); length of
