SHORE FISHES OF GALAPAGOS ISLANDS 349 



Range. Panamic region of the Eastern Pacific, ranging vertically 

 from loo to 2,000 fathoms. 



One mutilated specimen taken from the stomach of a Thunnus 

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

 with Garman's description of Maurolicus lucetius, 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 back. 



The species is close to Zalarges nimbarius 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. 

 lucetius. 



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

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

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

 2 families are really distinct.
