Siganus fuscescens (Houttuyn). 



Large series, mostly young. These identical with material from 

 Bacon, P. I., upon comparison. All have a dark shoulder-blotch 

 and dark spots or blotches on trunk. 



Siganus corallinus (Valenciennes). 



One which cHffers slightly from a Sumatran example in the smaller 

 dark spots on the head, doubtless due to age. Both agree largely 

 with Miiller and Schlegel's account. The alleged closely related 

 Chcetodon guttatus Bloch shows no dark spots on the head. Surely 

 the figure by Quoy and Gaimard of their Amphacanthus argenteus 

 cannot refer to this genus as it is shown with five dorsal spines and 

 three anal spines. Its trunk is clouded olive and brown, and there 

 is a white bar on the caudal peduncle. 



DROMBUS Jordan and Seals. 

 ULCIGOBIUS subgen. nov. 



Type Drombus maculipinnis sp. nov. 



Differs from subgenus Drombus in the higher spinous dorsal, larger 

 scales and very conspicuous pores on the sides of the head. Ventrals 

 joined, at least for their basal halves. 



Probably D. tutuilce Jordan and Scale belongs in the present group. 



{Ulcis, boil, with reference to the pores on the side of the head; 

 Gohius.) 



Drombus maculipinnis sp. nov. Fig. 27. 



Head 3; depth 3f ; D. VI-10; A. I, 7; P. i, 14; V. I, 5; scales 23 in 

 median lateral series from shoulder to caudal base and 3 more on 

 latter; about 7 scales between second dorsal origin and anal origin; 

 about 6? predorsal scales; head width If in its length; head depth 

 at occiput If; mandible 3|; first dorsal spine slightly less than head; 

 eighth dorsal ray If; last anal ray If; least depth of caudal peduncle 

 2yV; pectoral 1; ventral If; snout 3f in head measured from upper 

 jaw tip; eye 4|; maxillary 3|; interorbital about 2 in eye. 



Body moderately long, compressed though little robust anteriorly 

 and deepest about second dorsal origin. Body edges all rounded 

 convexly. Caudal peduncle compressed, slightly longer than deep. 



Head large, elongate, profiles similar, cheeks and lower sides 

 greatly and evenly swollen backward, with upper head surface more 

 constricted than lower. Snout convex over profile and surface, 

 length f its width. Eye moderate, superior, advanced, largely 

 directed upward. Mouth small, broad, gape extends about first 

 I in snout. Mandible broad, protrudes, rather shallow. Lips thick,
