12. Sphagebranchus gjellerupi n. sp. 



Height more than 40; head 11.7, 4.1 times in trunk; head 

 and trunk 1.2 times in tail. Eye small, about 12, nearly twice 

 in snout, situated above middle of cleft of mouth. Posterior 

 nostrils a slit in the border of the upper lip, looking downward, 

 below front border of eye; anterior nostrils in short tubes on 

 the ventral surface of the prominent part of the snout. Snout 

 pointed, about 6 times in head, its prominent part surpassing 

 the lower jaw with about one eye-diameter. Cleft of mouth 

 4.3 times in head, reaching behind eye. Dorsal and anal low, 

 increasing in height posteriorly on tail, where they end oppo- 

 site to each other near end of tail. Teeth pointed, uniserial, 

 a group of about 3 on the intermaxillary plate. Gillopenings 

 small, vertical slits, slightly longer than eye; the distance of

8. Fam. NEMICHTHYIDAE. 



Slender, more or less compressed, very elongate, tapering 

 to the end of the tail, which may be filamentous. Anus near 

 gillopenings or farther behind. Scaleless, lateral line with or 

 without pores. Dorsal and anal long and confluent with the 

 reduced caudal or extending to the end of the filamentous 

 tail. Pectorals well developed but small. Snout produced, but 

 extremely slender, more or less recurved upward l ), formed 



i) It is possible that the curve upward formed by the snout and downward 

 by the lower jaw is only a consequence of the manner in which the specimens 

 died or were preserved. We offer this opinion with regard to the specimen of 

 Nemichlhys scolopaceus, which was taken alive and has been described and figured 

 by ROULE (Ann. Inst. oc&mogr. I. fasc. 6, 1910). In this specimen the jaws 

 are straight (see p. 329).
