free in front. Nostrils together, near last f in snout length, anterior 

 simple pore and posterior exposed in crescent. Interorbital broadly 

 convex. Suborbitals well developed, entirely covering cheek, and 

 smooth. Hind preopercle edge slightly inclined back. Opercle 

 large, smooth, and with broad cutaneous edge to gill-cover. Parietal 

 fontanel rather broad and extends to occiput from frontals. 



Gill-opening extends forward about opposite first third in eye. 

 Rakers about 10+15, lanceolate, slender, about f length of filaments, 

 and latter about 1| in eye. Isthmus narrow, constricted in front, 

 surface convex. Branchiostegals subequally large, moderate. 



Fig. Q.—^dontostilbe madeiroe Fowler. (Type.) 



Scales large, all well exposed, in lengthwise series parallel with 

 I. 1., each with few radiating striae, and of mostly uniform size. 

 Caudal base with scales smaller than elsewhere. A few scales 

 basally along front of anal. Free pointed axillary scaly ventral flap, 

 and its length nearly 3 in fin. L. 1. complete, slightly inferior along 

 sides, though nearly straight. Tubes simple, well exposed, though 

 extending about half way over exposures of scales. 



Dorsal inserted nearly midway between snout tip and hind edge 

 of adipose fin, first branched ray longest, and fin reaches If to caudal 

 base. Adipose fin nearly equals eye in length, inserted about last 

 I in space between last dorsal ray base and caudal base. Caudal 

 rather large, well forked, and pointed lobes equal. Anal inserted
