Description 



D. 15 (14-16); A. 13-14 (12); P. 13-14; AO 6-7 + 5-6 (7), total (11-13, rarely 14); gill rakers 

 6-7 + 1 + 12(10-13), total 18-19 (17-21); vertebrae 38 (37-39). Correlated counts of AO 

 photophores and of gill rakers are given in Table 43.

Characters given for the genus will also serve for the species. Fraser-Brunner ( 1949) 

 provided a moderately detailed description of the holotype of//, candens. Rolf L. Bolin pre- 

 pared a considerably more detailed description of the holotype (unpublished) and kindly made 

 it available to me. As H. candens is poorly known, and as the two descriptions differ somewhat 

 (see Discussion), it seems advisable to present Bolin's description verbatim. 



Description of the holotype of Hintonia candens, 78.3 mm (Fig. 205) in the British 

 Museum, Natural History, taken at Discovery Station 1774 in the southeastern Atlantic 

 Ocean between 41°50.0' S, 00°01.7' E and 45°54.3' S, 00°03.3' E, between 400 and 650 m: 



Body heavy, robust throughout. Snout rather pointed, markedly protruding, mouth 

 definitely inferior, lower jaw somewhat shorter than upper, slightly included. Maxillary 

 not expanded posteriorly, ending in a rounded point, bent slightly downward, extending 

 about 1.1 orbital diameters behind orbit, about 0.4 of its length lying behind a perpendicu- 

 lar to mouth drawn through posterior margin of orbit. Premaxillary and dentary with 

 narrow bands of cardiform teeth, the inner ones somewhat enlarged in the premaxillary 

 and developed into quite heavy canine-like structures on the dentaries. Palatine teeth in a 

 single series, about equal in size to the outer teeth of the jaw. No teeth on vomer. 

 Pterygoid teeth rather widely scattered, the dorsal ones much enlarged as in Lampadena. 

 Opercular margin ending in a somewhat pointed flap, its upper portion bearing a feebly 

 ctenoid lobe. Gill rakers moderately long but rather heavy, this posterior surfaces con- 

 spicuously toothed. 



Origin of dorsal about midway between snout and AOp,. Anal origin slightly behind 

 end of dorsal base. Adipose fin slightly behind end of anal base. Pectoral base on a vertical 

 midway between snout and anus. Fin broken, probably extending to, or slightly beyond, 

 ventral base. Ventral base slightly posterior to dorsal origin, fin extending about to VO.v 

 Body scales in general cycloid, those of the lateral line somewhat cremate and displaying a 

 deep posterior notch. 



A moderately prominent Dn under anterior portion of frontal margin. A very deeply 

 embedded Vn appears to be present. OPi deeply embedded opposite lower end of premaxil- 

 lary. Op2 slightly larger than adjacent body organs, somewhat above end of premaxillary. 

 A rather well developed Bu about on level of lower orbital margin and somewhat behind 

 the eye. PLO almost directly over the base of upper pectoral ray and about midway 

 between it and lateral line. PVO, somewhat in advance of upper part of lower end of 

 pectoral base. PVO2 immediately below and in front of lower end of pectoral base. Six PO.
