Family CONGRIDAE 

 Genus CONGER Cuvier 



CONGER WILSON! (Schneider). 



Recorded from Honolulu by Fowler. A species described from 

 Australia, unlaiown to recent writers. 



Family MURAENIDAE 



Genus GYMNOTHORAX Bloch 



The genus Gyinnothorax may ultimately prove to be divisible into 

 several genera, perhaps, however, not Avholly along the lines attemj)ted 

 by McClelland, Kaup, and others. Two species, MuraeTia nudivomer 

 Giinther, and GymnotJiorax xanthostomus Snyder have no teeth on 

 the roof of the mouth. These have been separated by Fowler from 

 Gyinnothorax proper, under the generic name of Ahynnodontophis^ 

 the type being Gyinnothorax stigmanotus Fowler^ from the West 

 Indies. 



GYMNOTHORAX HEPATICUS (Ruppell). 

 GYMNOTHORAX TILE (Buchanan-Hamilton). 



These two Morays are recorded by Fowler from Honolulu. 



Genus SIDEREA Kaup 



{Type. — Muraena Hiderea Richardsou=J/«rae«a incta Ahl.) 

 SIDEREA PICTA (Ahl). 



In this abundant species the vomerine teeth are very small, rounded, 

 and arranged more or less in the form of a Y. For the group thus 

 defined the name Siderea (later spelled Sidera) may be revived. 

 Here belong, in addition to 'picta^ other Hawaiian species, Gyinno- 

 thorax steindachneri Jordan and Evermann, G. hilonis Jordan and 

 Evermann and G. nuttingi Snyder. 



Genus ECHIDNA Forster 



{Tii[)c. — Gymnothorax echidna Schneider=Muaraena nehulosa Ahl and Mura- 

 ena variegata Richardsou ) . 



The Morays with the teeth mostly bluntish, hitherto grouped under 

 the name of Echidna Forster, constitute several fairly well marked 

 groups; three of them occur in the waters of Hawaii. 



The first is represented by the typical species of the genus Echidna, 

 E. nehulosa (Ahl). In this, and in others belonging to the same 

 group, there is a single row of conic but sharp canines in the front 

 of the upper jaw, one or two rows of blunt lateral teeth above, two or 

 three blunt canines on the anterior part of vomer, and a narrower 

 band of molars in but one or two series runnino: back along the
