slender, 2+ in head, the rays a little higher ; anal lower, the rays 3^ to 4 in 

 head; pectorals reaching anal, IJ in head; vcntrals 2\\ dorsal and anal 

 free from caudal. Color in life, according to Evermann & Jenkins, yel- 

 lowish; 5 quadrate spots of darker extending from dorsal to a line drawn 

 from middle of eye to lower base of caudal, the anterior one above tip of 

 pectoral; median line of side with a more or less distinct series of small 

 spots ; a short dark vertical line behind the eye ; a dark blotch in front of 

 origin of dorsal fin and another on humeral region; underside of head 

 with 2 ill-defined dark bands; dorsal fin more or less speckled with black, 

 the anal with a narrow white border above which is a broader band of 

 deep brown. Six specimens, the largest about 3 inches long, were obtained 

 at Guayuias, Sonora, by Drs. Evermann & Jenkins, in 1887. One of these; 

 (No. 412, L. S. Jr. Univ. Mus.), examined by us, is the type of the present 

 description. The large mouth distinguishes this species at once from 

 Hypsoblennius striatus, with which it has been identified. The species is 

 intermediate between typical Chasmodes and Hypsollennius, and. its discov- 

 ery may make it necessary to merge the latter in Chasmodes. (Named for 

 Dr. Oliver Peebles Jenkins.)

D. 27; A. 15. Form of Chasmodes losquianus: Lower jaw slightly longer 

 than the upper. Dorsal and anal free from caudal ; anal fin highest ante- 

 riorly. Body with 4 distinct brownish bands, a fifth broader and less 

 marked on the neck; 4 round yellowish spots along base of anal; head 

 spotted with blackish. (Wood.) Habitat uncertain, probably South 

 Atlantic coast of the United States; not recognized by recent collectors; 

 very likely based on the female of C. 1)os<ptianus, with the caudal torn from 

 the other veriical fins, (quadri-, four; fasciatus, banded).
