SHORE FISHES OP^ GALAPAGOS ISLANDS 349 



Ra>ige. — Panamic region of the Eastern Pacific, ranging vertically 

 from 100 to 2,000 fathoms. 



One mutilated specimen taken from the stomach of a Thutiniis 

 caught a few degrees north of the Galapagos Archipelago. It agrees 

 with Garman's description of Matirolicus hiccthis^ but differs from 

 the figure in the possession of an adipose fin. A few patches of thin 

 cycloid scales are present on the caudal peduncle and hack. 



The species is close to Zalarges ni7nbarius Jordan & Williams, 

 differing from it in the larger head, the shorter and deeper body, and 

 in the larger ventral photophores, which are crowded and juxtaposed. 

 We have examined the type of Z. nimbarius and find that it possesses 

 a well developed adipose fin and a few large cycloid scales. Neither of 

 these characters is shown in the figure of the type. The fins are 

 not well preserved, but the anal has apparently 15 rays, as in Z. 

 hccetius. 



On the strength of the absence of pseudobranchias and of the pres- 

 ence of scales, we have placed this genus in the Chauliodontidos. It 

 is closely related to the Maurolicidae, and it is doubtful whether these 

 2 families are really distinct.
