second row of shorter ones. Dorsal without a spine, its second ray soft 

 and segmented though not divided, its origin a little behind ventral base, 

 equidistant from base of caudal and front of eye. Pectoral pointed, 

 reaching % to ventral, ventral a little more than half way to anal, anal 

 not reaching caudal by a distance equal to half head, caudal deeply forked. 

 Apparently a low keel on belly behind ventrals and none in front of them 

 (all three specimens are so cut as to make this difficult of determination). 

 Lateral line complete, dropping to the lower part of the side with an 

 abrupt flexure over end of pectoral, rising gradually on the peduncle to 

 terminate in the center of same. Scales of moderate size on the body 

 becoming smaller posteriorly, about 75, 11 between lateral line and dor- 

 sal, 3 between lateral line and ventrals. Dorsal 9. Anal 15. 



Brownish along the back, silvery elsewhere. Named for Mr. and Mrs. 

 Roy Chapman Andrews in recognition of their recent zoological explora- 

 tions in Yunnan. Besides the type we have two smaller specimens of 

 114 and 116 mm. with the same data. The type is a female with eggs. 



Acanthorhodeus grahami, sp. nov. 



Close to Acanthorhodeus atranalis Giinther, but more slender. Depth 

 3.0 to 3.3 (instead of 2.5); 4^ scales between lateral line and vent (in- 

 stead of 5%). Dorsal soft rays 11 to 13, anal 10 to 11. Scales 37 to 39. 

 Teeth in one row, 5, slender, hooked, denticulate. 



The type, No. 7029, American Museum of Natural History, was col- 

 lected at Yunnan-fu, Yunnan, China, by Mr. John Graham. It is 54 

 mm. long to base of caudal. Head 4.0 in this length, depth 3.1. Eye 

 2.7 in head, snout 4.1, interorbital 3.4, maxillary 3.5, depth of peduncle 

 2.5, dorsal spine 1.6, longest ray 1.4, anal spine 1.7, longest ray 1.6, pec- 

 toral 1.3, ventral 1.5, caudal about 1.0. 



Body compressed. Mouth oblique, lower jaw slightly projecting, max- 

 illary not quite reaching front of eye, upper jaw strongly protractile, 

 angle of mandible under front of eye, no barbels. Upper profile straight 

 to nape, thence convex to dorsal, thence concave to caudal ; lower profile 

 oblique to angle of mandible, thence horizontal to gill opening, thence 

 gently convex to anal, thence slightly concave to caudal ; peduncle taper- 

 ing, 2% times as long as deep. Vent just behind base of ventrals with a 

 conspicuous papilla. Pectoral narrow and pointed, just reaching ventral, 

 ventral just not reaching anal, dorsal and anal slightly concave above, 

 caudal forked. Dorsal origin behind ventrals, midway between snout 

 and base of caudal; anal origin under middle of dorsal. Second dorsal 

 and anal rays developed as strong sharp spines, but not serrate. Scales 

 loosely attached, lateral line complete, below the center of the front of 

 the peduncle. Scales 38, 4^ between lateral line and vent, 6% between 

 it and dorsal. Dorsal II 12. Anal II 10. 



Color pale. Sides silvery, the silvery forming an ill-defined stripe pos- 

 teriorly, with a faint dark central streak. Most of the anal occupied by 

 a large black semi-oval terminal blotch, which does not extend on the 

 spines or posterior rays.
