﻿RHOGEESSA PARVULA. 



125 



Dobson and most subsequent authors have wrongly applied the spe- 

 cific name parvula to this species. So far as known B. parvida is 

 restricted to the Tres Marias Islands. 



[The following species is not North American^ hut is introduced here to complete 

 the account of the genus Jxhogeessa.^ 



RHOGEESSA MINUTILLA Miller. 



1896. Vesperugo imrrnJns Robinson, Proc. U. S. National Museum, XYIII, p. 651 (not 



Rliogeessa parvula H. Allen). 



1897. FJiogccssa minutilla Miller, Proc. Biol. Soc. Washington, XI, p. 139, May 13, 1897. 



Type locality. — Margarita Island, Venezuela. (Type in U. S. National 

 Museum, ^o. 63216.) 



Geographic distrihiUion. — This species is probably confined to Mar- 

 garita Island. 



General characters. — Similar to Rhogeessa tumida, but considerably 

 smaller (forearm, only 25 mm.). 



Uars. — The ears of the type (when relaxed by soaking in water) 

 appear to be smaller and narrower than in B. tumida, but otherwise not 

 peculiar. 



Memhra7ies, feetj and distrihntion of fur. — As in B. tumida. 



Color. — Fur everywhere light yellowish brown to base, the hairs on 

 the back tipped with chestnut. The color appears to differ slightly 

 from that of B. tumida^ but I have too few skins to make an adequate 

 comparison. 



Sliull. — The skull of the type and only known specimen is so much 

 injured that its characters can not be determined with certainty, but it 

 appears, to be smaller and relatively narrower than that of B. ttmida, 

 Greatest length, 11.8 j length of mandible, 9; upper tooth row, 5 ,• lower 

 tooth row, 5.6. 



Teeth. — The teeth are essentially as in B. tumida. 



Measurements'. — The measurements of the type specimen are given in 

 the table on page 129. 



Speciynens examined. — One, the type. 



General remarlcs. — Bhogeessa minutilla is a small insular form most 

 closely related to B. tumida^ but apparently perfectly distinct. So far 

 as I know the genus Bhogeessa has not yet been recorded from the 

 mainland of South America, where, however, it doubtless occurs. 



RHOGEESSA PARVULA H. Allen. 



1866. Bhogeesfia parvula^. AHqm, Proc. Acad. Nat. Sci. Phila., p. 285 

 Tpye locality. — Tres Marias Islands, Mexico. 

 Geographic distrihution. — Tres Marias Islands. 



Characters.— As I have seen no specimens of this species, I quote 

 the original description entire. It is as follows: 



"Ear sub-acute at tipj lips whiskered j eyes very small, each fur- 

 nished with a Avart above; similar growth seen beneath chin. Fur 

 above silky, not thick, of a light greyish-brown at basal third, fawn-
