pharyngeal teeth in two patches, conical. Dorsal fin long, almost 

 entirely composed of spines ; anal with one spine and many soft 

 rays; ventrals rudimentary, jugular; no pectorals; caudal tin 

 distinct, connected with the dorsal and anal. Minute, scat- 

 tered, rudimentary scales, imbedded in the skin, present on the 

 caudal region of the body only, A single, indistinct, median 

 lateral line. 



Ophioclinus devisi, sp.nov. 



B. V. D. 70/3 ca. A. 1/55 ca. V. 1/2. C. 12. 



Length of head 6f to 7, height of body 15 to 15| in the 

 total length ; height of head rather less than its width. Eye large 

 its diameter 5| to 5f in the length of the head ; snout short and 

 rounded, its length about seven-eighths of the diameter of the eye, 

 interorbital space flat, li to 1^ in the same. Lower jaw the 

 longer ; cleft of mouth oblique, the maxilla reaching to beneath 

 the middle of the orbit : upper profile of snout convex, of 

 occiput flat ; opercular region elongate, tumid. Series of 

 large open pores around the orbits, the margins of the 

 preopercles, on the occiput, and the nuchal region. Teeth in the 

 upper jaw stout and conical, in three series anteriorly, the outer 

 of which is continued on the sides; in the lower jaw in a single 

 series, much stronger than those of the maxillaries ; a few 

 scattered teeth on the vomer ; pharyngeal teeth similar to those of 

 the upper jaw, arranged in two arcuate patches. The dorsal fin 

 commences a short distance behind the opercular flap ; the spines 

 are strong, and, with the exception of a few anterior ones which 

 are short, subequal in height, about a half of that of the body: 

 the distance between the snout and the ox-igin of the anal is 2^ 

 in the total length ; anal papilla little developed. A single lateral 

 line along the middle of the body, straight. 



Colours (in spirits). — Uniform reddish brown, the occiput and 

 opercles with a yellowish tinge. 



This interesting species belongs to the Xiphidiontid section of
