CCELORHYNCHUS OCCA, Goodk and I!ean. (Fif;iiros 332, 333, 337.) 



Macrnnts occa, Goode and Beax, Proc. IT. S. Nat. Mus., viii, 1885, 595. — Gi'-NTnEU, Cliulleu;j;u.r Export, xxii, 

 124 note 5. 



A species with an exceedingly elongate snont, nearly twice as long as the eye, witli a 

 black Hap between the nostrils ; with the angle of the mouth nearly reaching to the vertical 

 from the posterior margin of the orbit; the head contained 3.^ times iu total length and 

 equaling twice the greatest height of body. The ridge of the head is very strong and 

 continuous from the snout to the angle of the preopercle, having, also, strong supraocular 

 and occipital ridges. 



Eye nearly round, its horizontal diameter ^ length of the head and ucjual to interor- 

 bital space. 



The ventral originates under the middle of the first dorsal, and extends to the fourth 

 ray of the anal. Tlie distance from ventral origin to vent is contained 3^ times in length 

 of head. 



The second spine of the dorsal is weak and smooth, its length equal to postorbital jiart 

 of head, its base slightly less than the distance between first and second dorsals. 



Squamation excessively rough, each scale bearing about 5 large spines besides many 

 smaller ones, the median sitinc of the large series being much the largest. Five rows of 

 scales between origin of dorsal and lateral line, 19 from vent forward to lateral line and 12 

 backward. 



Barbel one-fourtli as long as snout. 



M. occa appears to be a near relative of ('. aflanticKs, and is very close also to M. 

 japoiiicioi of \'aillant (Exp. Sci. Travaillcur et Talisman, Poissons, 254, j)!. xxi, lig. I), 

 identified by him, without adcfiuato grounds, with M. japonic uh, Schlegel. 



This species has scales similar to tho.se of Macnirus Fabricii, there being a strong 

 median Keel formed by a series of 3 to 5 si)ines, of which the last is flic largest. The surface 

 of each scale also contains about 4 or more lateral ridges formetl by series of short spines. 

 In a much larger example. No. 37334, measuring 18 inches in length, the lateral series of 

 keels have greatly increased in nunilx-r, tlie individual si»ines have become more ]irominent, 

 so that the median keel has become less conspicuous than in tlie type. In the larger spec-
