Family OPHICHTHYID£. 



SPHAGEBRANCHUS Bloch. 



148. Sphag-ebranchus flavieaudus Snyder. Maui, Hawaii. 



DALOPHIS Rafinescpie. 



149. Dalophis long-ipinnis (Kner & Steindachner). Samoa. 



This small species, very slender in form and having the dorsal inserted in advance of the gill- 

 opening, is known to us from a very young example taken at Apia. 



150. Dalophis misolensis ( Giinther). Misol. 



Ophichthys misolensis Giinther, Ann. Mag. Nat. Hist., x, 1872, 426, Misol. 



MICRODONOPHIS Kaup. 



151. Microdonophis fowleri Jordan & Evermann. Hawaii. 



152. Microdonophis macgreg-ori Jenkins. Hawaii. 



153. Microdonophis polyophthalnius Bleeker. Hawaii; East Indies. 



This species differs from the type of Microdonophis in having the dorsal inserted over the middle of 

 the head. The body is uniformly colored. 



BASCANICHTHYS Jordan & Davis. 



154. Bascanichthys pinguis Giinther. Solomon Islands. 



Ophichthys pinguis Giinther, Ann. Mag. Nat. Hist., x, 1872, 425, Solomon Islands. 



CALLECHELYS Guichenot. 



155. Callechelys luteus Snyder. Molokai, Hawaiian Islands. 



156. Callechelys filaris (Giinther). Misol. 



Ophichthys filaris Giinther, Ann. Mag. Nat. Hist., x, 1872, 425, Misol. 



LEITJRA1TOS Bleeker. 



157. Leiuranus semicinctus (Lay & Bennett). 'Ata'ata uli. Hawaii; Japan; East Indies. 



Of this species we have one large specimen from Apia. Its coloration is wonderfully close to that 

 of C'hlevastes colubrinus, but the black bands are broader than in the latter, and most of them do not 

 meet the fellow on the belly. This species is widely diffused, occurring in company with the two 

 species of Clilemstes, both of which are colored remarkably like it. 



158. Leiuranus cobra (De Vis). South Seas. 



Ophichthys cobra De Vis, Proe. Linn. Soe. N. S. W., 18S4, 455, South Seas. 

 This species is said to have the head one-tenth of the length of the trunk. In other respects it 

 agrees with Leiuranus semicinctus, with which it is probably identical.
