streak bordered with a brown line extending in front of eye to snout; 

 upper lip with two white streaks bordered by brown lines; cheek 

 brownish, with a pale streak below eye; lower lip with 3 brown 

 blotches; median fins brown spotted; spinous dorsal with a blackish 

 blotch. 



Color when alive. — The following notes are based on a color drawing 

 from the Philippine Albatross collections. Bars on sides of body 

 bluish brown; back tinged with greenish brown; spot on spiny dorsal 

 dark blue bordered with a white edge ; pale streaks in front of eye and 

 on upper lip orange; pelvics and ventral sides of body tinged with 

 pale blue; distal edge of soft dorsal pale greenish, below which are 

 reddish brown spots. 



Ecology. — This species inhabits sandy areas. 



Family TRICHONOTIDAE 

 By Leonard P. Schultz 



This is a "catch-all" family to which several genera have been 

 referred. Schultz (Journ. Washington Acad. Sci., vol. 31, pp. 269-272, 

 1941; U. S. Nat. Mus. Bull. 180, pp. 260-267, 1943) referred several 

 genera of sand-inhabiting fishes to the family Trichonotidae merely 

 as a practical convenience in identifying this variable group of genera. 

 In the key presented by Schultz in 1943, section 2b should have 

 followed section 6b, and in 1941 2b should follow 3b. These were 

 transposed through a typographical error. The genus Kraemeria 

 was recently studied by Gosline (Pacific Sci., vol. 9, pp. 158-170, 

 figs. 1-7, 1955) and shown to be a gobioid fish. Gohitrichinotus 

 radiocularis Fowler (U. S. Nat. Mus. Bull. 100, vol. 14, pt. 2, pp. 

 85-87, fig. 22, 1943), from the Phihppines, with united pelvic fins, 

 appears related to Kraemeria. 



The problem of how many families to recognize in this relationship 

 cannot be determined at present, so little is known about the osteology 

 of the diverse genera referred to the trichonotid-like fishes; however, 

 it can be said, at least, that a separate family for each genus should 

 not be recognized. 



The following key was intended as a practical aid for identifying 

 the peculiar genera that are more or less related to the trichonotid-hke 

 fishes. The members of this relationship are distributed throughout 

 tropical seas and live mostly in sandy habitats, or at least are bottom 

 dwellers.
