Recently Mr. August Busck, of the Bureau of Entomology, U. S. 

 Department of Agriculture, spent several months in the West Indies 

 in the interests of that Bureau. While in the interior of Santo 

 Domingo, some 40 miles northwest from the capital, he collected a few 

 small fishes from a small brook in the San Francisco Mountains. These 

 have been turned over to us by Mr. Busck for identification. 



Although the collection is very small, containing but (> specimens, 

 it proves to be of nuich interest in that 3 of the -t species represented 

 appear to be entirely new. 



All the specimens are in fair condition. The following is a list of 

 the species represented, with descriptions of those believed to be new: 



PLATYPCECILUS PERUGIA Evermann and Clark, new species. 



Head 4 in body; depth 3.4; eye 3 in head; snout 3.4; interorbital 2; 

 D. 8; A. T; Br. 6; scales 28-8, 12 in front of dorsal. 



Body short, greatly compressed, especially posteriorly, the dorsal 

 contour gently arched from nape to origin of dorsal fin; the ventral 

 outline strongly arched from tip of snout to origin of anal, the sides 

 of the long, greatly compressed caudal peduncle nearly straight; least 

 depth of caudal peduncle 1.5 in head, and 2 in its length from posterior 

 end of base of dorsal; head rather small, broad and fiat above, rather 

 sharp and wedge-shaped in lateral profile; mouth a very small straight 

 transverse slit at tip of snout, somewhat above level of middle of 

 orbit; premaxillaries very protractile; when drawn out the mouth 

 assumes the form of a short, round tube; lips thin, the lower somewhat 

 cleft; teeth minute, conical, clear in color, apparently in one row along 

 the edge of the lower jaw, in the movable bones of which they are 

 loosely set. 



Dorsal rather short but high, its longest ray 1.75 in head, its base 2, 

 its origin midway between tip of snout and middle of caudal fin; anal 

 similar, set somewhat farther back, its origin about under the middle
