No. 16,032, A. N. S. P., type of G. nigrocastaneus Cope. Cope 

 says "dorsal fin commencing above a point three lengths of the gape 

 behind the end of the muzzle," which is not true of his type. The 

 latter shows the gape 2§ to dorsal origin. The account, by Jordan 

 and Davis, of E. nigricans 16 varies somewhat from my example, as 

 they give the gape 2 in the head, mine showing clearly 2\. These 

 writers also evidently had the type of G. umbrosus Poey for com- 

 parison, and while they state in their description that the tail is 

 slightly longer than the rest of the body, Poey states that it is shorter. 

 Poey's figure shows the jaws equal, the gape half way to the gill- 

 opening, dorsal origin over gill-opening, and coloration marbled. 

 Further, the specific name notes the animal as black, Giinther giving 

 the coloration as uniform black. 17 It would appear likely Cope's 

 species has not been demonstrated as identical with E. nigricans. 



Muraena helena Linmeus. 



Three from Italy. 



Muraena clepsydra Jordan and .Evermr nn. 



One from Panama (Ruschenberger). Also five others without

Head 1\; depth 16|; head width 4| its length; head depth 2\\ 

 snout 6|; eye 9§; mouth 2§; interorbital 11; head Z\ to vent. 



Body long, rather deep, well compressed with surfaces of sides 

 moderately or slightly convex, and rather deep tail tapering a little 

 only at end rather suddenly. 



Head compressed, a little swollen behind and at occipital region 

 just behind eyes so that upper profile at that point rather deeply 

 concave, sides rather flattened and scarcely constricted below. 

 Snout with profile and surface rather evenly convex, somewhat 

 conic in general form, basal width \\ its length. Eye a little ellip-
