NO. 1907. NEW CYCLOOASTERID FISHES— GILBERT AND BURKE. 355 



diameter of eye 4; "width at angles of mouth 17.. '3; distance from tip 

 of snout to end of maxillary 15; length of gill slit 7.5; distance from 

 tip of snout to disk 18; to anus 38; diameter of disk 11; distance 

 from disk to anus 0.5; from anus to front of anal fm 0.5; length of 

 longest pectoral ray 10. 5; of shortest ray in notch 8. 



Dorsal 44; anal 34; pectoral 40. 



Body deepest in front of dorsal, tapermg rapidly backward from 

 middle of second dorsal. Head thick, only moderately depressed, 

 its width greater than its depth; cheeks swollen; maxillary reacliing 

 vertical from posterior margin of eye ; anterior nostril in a thick tube ; 

 posterior nostril without a tube. Teeth weakly trilobcd, in about 

 ten oblique rows in the half of each jaw. Gill slit extending down in 

 front of four pectoral rays. 



First seven dorsal rays separated off by a deep notch; caudal trun- 

 cate; anal joined to caudal for not more than one-seventh of the 

 length of the caudal; dorsal only slightly comiected to the caudal; 

 pectoral notched, the lower lobe consisting of seven rays and extend- 

 ing slightly past disk. Vent separated from disk by diameter of disk. 



Color olive brown above and on sides, paler below; fins unmarked, 

 colored the same as the body. 



In addition to the type, two young cotypes 28 mm. long were 

 obtained m the same locality. In these the vent is much farther 

 back, almost immediately in front of the origin of the anal. One of 

 the cotypes has largo scattered papillae, most numerous on upper 

 anterior part of trunk. These may develop "thumb-tacks" in 

 adults.
