30 Fifi/ieri/ Jhrrrd for Scoflmid. 



Bars may be sometimes traced on tlie sides, but often they are not 

 at all clear. Three were noted in one fish. Tlie first came down posterior 

 to the operculum ; the third was located below the soft part of the 

 dorsal fin, while the second bar was located about mid-way between the 

 two former. Several black or amber blotches were observed on the 

 dorsal fin. The front pai*t of the inside of the mouth is white ; the 

 pharynx is black or blue. The under edge of the gill-cover and 

 branchiostegal apparatus was whitish. 

 The peritoneum is jet black. 



Stellate black pigment corpuscles were observed on the wall of the 

 stomach of one fish. 



The urinary bladder is very small. 



The swim-bladder, as Delaroche* pointed out, is absent, 

 Fig. 106 represents a specimen of this species. The correct number 

 of fin-rays is not shown in every case. The scales are diagrammaticall_y 

 represented. 



The eyes are ver}^ large. The orbit is oval. 



The jaws are nearl}- equal when the mouth is closed; the 

 mandible does, however, project a little in front of the premaxill^e. 

 The horizontal membrane is present inside the lip of each jaw ; it is 

 narrow. Teeth are present on the vomer and palatines, in addition to 

 the premaxillge and dentaries. The teeth are all small. 



The short ridge over the eve is often toothed, as many as six or 

 seven teeth being made out. Sometimes it does not show teeth dis- 

 tinctl3^ but is simpl}^ a rough ridge. This condition may occur on one 

 side of the fish, while three well-defined teeth ma}^ be present on the 

 other side. 



The head in side view is gently rounded. 



The top of the head is depressed. The interorbital space is bounded 

 on either side by the prominent ridge which forms the upper edge of 

 the orbit. It is longitudinally hollowed out and bears, projecting from 

 its sloping sides, two prominent ridges shown in rd., Fig. 103. The 

 interorbital space in Sebastes is flat, and the two secondary longitudinal 

 ridges are absent. 



The scales are ctenoid (Fig. 99). No scales were present on the out- 

 side of the lower jaw. 



The number of pyloric ceeca was in two cases seven, and in one 

 case six. 



Dorsal Fin. — The dorsal fin consists of two parts — a longer portion 

 composed of spines, a shorter portion consisting of soft rays. In ten 

 fishes only a slight variation was found in the number of fin-rays. In 

 each of eight fishes the rays numbered 12 spines and 13 soft rays, 

 while in two specimens the numbers were 12 spines and 14 soft rays. 

 The 12th spine is longer than the spine preceding it. In one fish 

 the longest spines were the 3rd to Gth. 



The first two spines and the last two rays arise from a single inter- 

 spinous bone in each case. The last two rays are close together at 

 their bases. The angle between the last ray and the dorsal edge of 

 the body is filled with a little membrane. 



Anal Fin. — The anal fin consists of three spines and six soft rays. 

 These numbers were found in all the fishes in which the character was 

 noted, viz., eight. The first two spines and the last two rays arise
