GEN. LEPADOGASTER. CORNISH SUCKER. 249 



nus the membranes representing the pectorals form 

 one large disc, and behind that there is another 

 formed by the union of the ventrals. The body is 

 without scales. Only two British species are known. 



(Sp. 186.) L. Cornubiensis. Cornish Sucker. 

 This small species, the length of which does not usu- 

 ally exceed two inches and a half, appears to have 

 been first noticed in this country by Dr. Borlase, on 

 the coast of Cornwall. That is still the locality 

 where it occurs in greatest plenty, although it has 

 been noticed both in Scotland and Ireland. Pennant 

 calls it the Jura Sucker, specimens having been pro- 

 cured by him from the shores of that island. It is 

 frequently spotted, and there are two large ocellated 

 spots behind the eyes ; these however are not visi- 

 ble in the young fish. It is usually found about low- 

 water mark, adhering to stones, and is often left by 

 the tide. Mr. Couch says it spawns in March, and 

 that its food consists of crustaceous and other minute 

 marine animals. 



(Sp. 187.) J^' himaculatus. Two-spotted Sucker ; 

 so called from two marks on the sides, which, how- 

 ever, are not always very obvious, and in young 

 specimens are altogether wanting. This species sel- 

 dom much exceeds an inch and a half in length ; the 

 head depressed and the body tapering more than in 

 L. Cornubiensis. The prevailing colour is a fine red ; 

 under side flesh colour. It has been found at Wey- 

 mouth, Torcross in Devonshire, Polperro and Pen- 

 zance in Cornwall, and also in Ireland. It appears 

 to have been first described by Pennant, who states
