We have prepared a table of measurements of our three small 

 specimens with which are included measurements of typical C. 

 parallelus from Japan. The relative lengths of the different speci- 

 mens should be constantly considered when their measurements are 

 being compared.

i A pseudocaudal developed. 



(parallelus, in reference to the arrangement of the series of spinules 

 on the scales.) 



43. COELORHYNCHUS SPINIFER, new species. 



? Coelorhynchus maerorhynchus Weber, Fische der Si&o^a-Expedition, 

 1913, p. 162, pi. 4, figs. 2 and 2a (not a synonym of C. macrorhynchus 

 Smith and Radcliffe, as suggested by Weber on p. 671). 



This remarkable new species is related rather remotely to C. 

 parallelus; it differs from that species in having the orbit smaller; 

 the snout longer and with more convex sides; the spinules on the 

 scales notably longer and stronger, particularly on the ridges of the 

 head. C. spinifer is probably the most strongly spined species of the 

 genus. It was dredged at a greater depth than that inhabited by most 

 of the other species. (A specimen of Bathygadus multifilis was also 

 dredged at the type-station of this species.) 



Type-specimen. — Cat. No. 78226 U.S.N.M. :*65 mm. long to the end 

 of its whip-like tail, 66.5 mm. to the anus; Albatross station 5607, in 

 the Gulf of Tomini, Celebes (0° 04' S., 121° 36' E.) ; depth, 761 

 fathoms. 



Fin-rays — first dorsal, II, 9 ; pectorals, 19-18 ; ventrals, 7. 



The dorsal and ventral contours are not strongly arched, but con- 

 verge rather rapidly behind the trunk; the dorsal contour of the 

 snout is almost straight (a little concave in C. parallelus) ; the base
