SYNOPSIS OF THE FISHES OF MADEIRA. 11 



Crenilahrus luscus, nob. in Syn. Mad. Fish. 187 ; nee Yarrellii nee Linnrei. 



This also proves distinct from Mr. Couch's Scale-rayed Wrasse {Acantholahrus 

 Couchii, Cuv. and Val. 13. 248), to which, as figured by Yarrell for the Labrus luscus, 

 L. (a true Labrus, according to Valenciennes), I had formerly referred it. A still 

 nearer ally appears, however, to be Acantholahrus Palloni, Cuv. and Val. 1.3. 243 {Cre- 

 nilahrus exoletus, Risso, hand Labrus exoletus, L.). From this it differs in the extension 

 up between each of the spines of the dorsal and anal fins of generally four of the large 

 scales into a curious distinct and moveable imbricated appendage ; in the large dark 

 spot or patch on the hinder end of the spiny portion of the dorsal fin ; in having two 

 dark spots on each side at the base of the caudal fin, one on the dorsal, and another 

 fainter on the ventral line ; and lastly in the general colour. In the first and last of 

 these four points, it agrees better with Acantholahrus Couchii, Val. {Crenilahrus luscus, 

 Yarr., Brit. Fish. 1. 300) ; but it differs in the other two, is only half the size, and 

 whilst the dorsal and the anal fins have severally one spine less, the dorsal has one soft 

 ray more. 



Labrus reticulatus. 



This fish cannot be at present safely referred to the Ballan Wrasse of British Authors 

 (Labrus maculatus, BL), Yarr. 1. 275 ; although in size and form of body, no less than 

 in the peculiar lowness of the spiny portion of the dorsal fin, and abrupt production of 

 the soft part of the same, and of the anal fin, as well as in the number of the rays of all 

 the fins, there is a strong agreement. It will, I think, however, ultimately prove merely 

 a dark variety of that species. The colour is peculiarly sombre ; being a dark brown, 

 approaching on the back almost to black ; the whole beautifully reticulated with dark 

 chestnut-brown lines, forming a border to each scale, and leaving the centre pale. The 

 preoperculum was scaly. A single individual occurred in March 1838, and measured 

 sixteen inches in length. Its fin-formula was, 



D. 19 + 11; A. 3 + 9; P. 14; V. 1 + 5; C. I'^l'^l^'; B. M. 5. 



3 + 1 -H V. 



This individual has been deposited in the Society's collection. 



Ctenolabrus iris, Cuv. et Val. XIII. 236. Rariss. 



A most elegant and well-marked little species.
