Family PSENIM 



9. Ariomma evtermanni Jordan & Snyder, new species (Fig. I, text.) 



A second species of this peculiar genus is represented by one badly preserved specimen. It differs 



from Ariomma lurida in having a smaller head, shorter snout, smaller eyes, shorter gillrakers, and 



larger scales. The head is apparently naked and the caudal i- forked, characters which both 



species may, however, possess in common. The anal rays are evidently preceded by two spines in 



I. everma 



Head 3.4 in length measured to base of caudal; depth 4; depth of caudal peduncle 5.5 in head; 



1.7; snoui 3.3; interorbital space 3.3; dorsal xi-i, L5; anal u, 15; pectoral 25; scales in lateral 

 -cries about 38. 



Snout blunter and slightly more rounded than that of A. lurida; caudal peduncle shorl and 

 cylindrical; interorbital space very convex; eyes with thin adipose lids; maxillary not freely 

 protractile, rounded posteriorly, about equal in length to diameti r of eye, almost enl ealed 



beneath a broad, pendant, preorbital flap; jaws equal, each with a single row of minute teeth; vomer 

 and palatines without teeth; tongue large and smooth; gillrakers 7+19, short, slender, and point 

 pseudo-branchiae present; nostrils near tip of snout.

Pype. 



Head naked; scale- oi body large, cycloid, very small on caudal peduncle, extending forward on 

 occipital part of head almost to a point above posterior margin of eye. 



Origin of dorsal above posterior edge of base of pectoral; the spines slender, the longest i third or 

 fourth) contained 2.2 times in length of head; spinous and soft dorsals apparently connected by mem- 

 brane; base of anal long, nearly equal to length of head; first 2 ray- small and spine-like; last ray of 

 dorsal and anal pencillated, nearly disconnected like the finlets of Oligopliles, these fins extending an 

 equal distance posteriorly; pectoral 2 in head; ventral- pointed, 2.3 in head; caudal forked, the 

 lobes pointed, 1.4 in head. 



Color, probably dusky; operclewitha large blackish patch; lining of gill-chambers black; mouth 

 light. 



Type, no. 57783 D. S. National Museum, measuring 8 indies in length; from the market at 

 1 lonolulu. 



Named for Dr. Barton Warren Evermann, assistant in charge, Division of Scientific Inquiry, U. S. 

 Bureau of Fisheries, in recognition of his work on Hawaiian fishes. 



This genus does not belong to the Apogonichthyidse. It seem- rather to be an ally of Cubiceps, in 



;roup usually called Nomeidse; but as the generic name Nomeui ought properly to give waj to 

 Gobiomorus, we may call the group Psenidse. It differs from Slromateida chiefly in the separation of 



the dorsal lins. 



We may note here that the Hawaiian species oft scribed on page I 74 of the Hawaiian 



report, is Germo maeropterus (Schlegel), not '• i i figure is of the latter species.
