46 baillon's wkass. 



mottled with streaks and spots of very dark brown; tail with 

 cross bars, and, near the termination of the lateral line, an 

 ocellated spot. 



Dr. Gunther's account of Crenilahrus Baillonii is thus given : 

 "The height of the body is contained three times and a third, 

 or three times and a half in the total length. Cheek witli 

 two or three series of scales; the length of the snout is one 

 third of that of the head. The soft dorsal and the anal with 

 two black or blackish spots at the base. Back with five or 

 six dark cross bars, more distinct in young individuals. Oper- 

 culum without dark spot; base of the pectoral black. The 

 dorsal fin with fourteen firm and ten soft rays; anal three 

 firm and ten soft rays." 



"This species will be easily distinguished from its nearest ally, 



C. quinquemaculatus, by the larger scales on the cheek, and 



by the greater number of longitudinal series of scales above 



the lateral line. The characters by which the two species 



have been distinguished are constant in all the specimens 



examined. The anterior spot on the dorsal fin is the most 



distinct, whilst the others are paler, and may entirely disappear 



with age. The number of the anal rays has been incorrectly 



given by Valenciennes. This species has been found on the 



coasts of Lisbon and Mogader, as also in the British Channel." 



The Crenilahrus quinquemaculatus, here referred to, is a 



native of the Mediterranean, but has not been recognised as an 



inhabitant of our own shores. It is subject to much variety, 



and sometimes has a dark spot on the middle of the base of 



the caudal fin, (as in the fish we have described; but in our 



example it was ocellated, or marked with a pale border, as we 



have never seen in the Corkwing.)
