tubes, nearly median in depth of body and continuous. A number of 

 small pores on head. 



Dorsal inserted a little nearer tip of snout than l^ase of caudal or a 

 little before origin of ventral, and first developed ray highest, though 

 not reaching as far posteriorly as tip of last ray when fin is depressed. 

 Anal well posterior, inserted about midway between origin of ventral 

 and base of caudal, and first developed ray, which is longest, reaching 

 well beyond last ray, when fin is depressed. Caudal damaged, evi- 

 dently little if any emarginate. Pectoral with first simple rays robust, 

 fin broad, rounded and reaching about f of space to origin of dorsal. 

 Ventral similar, only with first two rays simple and enlarged, and when 

 depressed reaching posteriorly about as far as tip of last dorsal ray or 

 almost to vent. Vent near tip of ventral well before origin of anal. 



Color in alcohol brown, clouded with large distinct blotches or areas 

 of deep brown, irregular though one distinct between dorsal and ven- 

 tral. Ventral surface a little paler brown than upper surface. A 

 brown streak from tip of snout to eye, and continued behind up to 

 occiput, and another down across side of head. These streaks all with 

 narrow pale brownish margins. Dorsal and anal brownish-white 

 clouded with dull blackish or blackish-brown. Anal similar, also 

 pectoral and ventral, though these fins all have more white and the 

 dark colors more diffuse. Iris slaty. 



Length 4J inches. 



Eight examples. 



These beautiful fish all vary in the markings, some having the pale 

 areas most pronounced, while in others the dark markings predominate. 

 In the young they appear best defined, some having the ventrals with 

 much black. 



HOMALOPTEROIDES gen. nov. 

 Type Homalopfera xvossinkii Bleeker.

 in advance.
