A'omerine teeth, while T. elougatus also has only four Instead 

 of six dorsal spines. In all other respects, however, they 

 agree with Hoplostethus, T. intermedius indeed being very 

 closely allied to H. mediterraneus, so that I think it better to 

 expand the limits of that genus to include them rather than 

 form an unnatural group by uniting Hoplostethiis and Tra- 

 chichthys. 



AUSTROBERVX GERRARDI. Guuther. 



(Plate viii.). 

 Beryx Gerrardi, Giinther, Ann. Mag. Nat. Hist. (5), xx., 

 1887, p. 238, fig. 



Br. 8; D. vi., 13; A. iv., 12-13; ?• 13; V. i., 7; C. 19; 

 1. lat. 36-39; 1. tr. 6 + II. Height its -2, head 2i-2f in 

 the length to the hypural. Eye 2|- in the head. Interorbital 

 width slightly less than f of the eye, and equal to the length 

 of the snout. Base of the anal f that of the dorsal which 

 equals the length of the head. Caudal peduncle i of the eye 

 and almost equal to the post-orbital portion of the head. 



Body short and deep. Upper profile very convex from the 

 snout to the first dorsal spine which marks its highest point. 

 The curve from the snout to the ventral fin is much less than 

 that of the back ; the line between the ventrals and the anal 

 is straight and bears 9-1 1 keeled scales which decrease in 

 size backwards. 



Maxillary reaching to below the posterior third of the eye, 

 stiliform anteriorly but very broad behind ; there is a small 

 rough patch of spines on the narrow portion which is in con- 

 tact with the supplemental bone, but the rest is smooth. 

 Supplemental bone with numerous ridges each ending in 

 spines. Turbinal bones bilobed and margined with sharp 

 spines. Preorbital denticulated, without a curved spine but 

 with a slight notch at its upper end to receive a blunt spine 

 projecting from the maxillary. Bones of the infraorbital arch 

 spine-like and roughened. Interorbital space narrowest above 

 the middle of the eye, becoming a little wider forwards, then 

 narrowing again towards the nostrils. Supraciliary edges 

 finely denticulated, terminating anteriorly above the nostrils ; 

 between these are two curved, slightly roughened ridges 

 which approach each other at either end and enclose a some- 

 what elliptical area, with truncate ends, which is 3J-4 times as 

 long as broad. Above the first third of the eye these ridges 

 each give off a branch which again divides and passes back- 

 wards ending in some rather strong spines some distance 

 before the suprascapular. 



Preoperculum with two parallel margins, the hinder borders 

 of which are serrated ; the angle of the inner margin is formed
