(velifer, in reference to the high dorsal.) 



26. COELORHYNCHUS SEXRADIATUS, new species. 



Type-specimen. — Cat. No. 78217, U.S. N.M. : a male 205 mm. in total 

 length (a small pseudocaudal developed), 66 mm. to anus, dredged 

 at Albatross station 5172. 



List of stations. 



Fin-rays — first dorsal, II, 8 (or II, 9) ; pectoral, 14 (or 15) ; 

 ventral, 6 — 6 (as also in 6 paratypes, but 6 — 7 in the only other one). 

 Pectoral and ventral rays fewer than in 0. notatus. 



Greatest depth of body, 1.78 (to 1.72) in head; width over pec- 

 toral bases, 2.30 (2.25 to 2.50), being a little less than the depth 

 of the body below the origin of the lateral line. In a smaller speci- 

 men, 55 mm. long to anus, the depth is 1.85 and the width 2.61 in 

 the head. 



The dorsal contour of the snout is concave ; the snout is broadest 

 at its base, its lateral contours converging forward in a curve less 

 convex than in C. maculatus and C. velifer, but rather more convex 

 than in C. notatus or triocellatus. The tip of the snout is sharp, as 

 the terminal plate projects beyond the margin of the following- 

 scales.
