A CORNISH FATTNA. 



MAOEUEA — (Long-tailed Division). 

 SCYLLARIDJE. 



Genus, Scyllarus — Fahr. 



Second pair of antennae having a broad disc-like plate instead 

 of an extended rod-like flageller. 



ScYLLARTTS ARCTus. — Liwi. ; Milne Edwards, Sid. des Crust., t. ij, 

 p. 282. 

 Several specimens of this very interesting animal have been 

 taken of late, one of which was at Polperro, and Mr. Couch had 

 the honour of announcing its first addition to the British fauna. 

 Since then it has been taken by Mr. Cornish at Penzance, and at 

 Plymouth near the entrance of the Sound. Two of these were 

 pregnant with spawn. Two also were taken in the stomach of 

 a cod fish. Those that I have seen were about four inches long. 

 The zoea of Scyllarus, according to Anton Dhorn are Phyllosoma. 



PALINURIBM. 



Genus, Paxinurus. — Fair. 



''The body almost cylindrical, in front a deep impression, having 

 on each side a prominent spine with others scattered about. The 

 legs compressed, all monodactyle." 

 Palinurus vulgaris — (Crawfish, or Eed Crab) — Couch; Leach; 



Fahr; Milne Fdtvards, Hist, des Crust., t. ii,p. 292; Leach, 



Malac, pi. 30. 



Cancer Homarus. — Pennant, pi. \\, fig. 22; Bell, Stalk-Fyed 

 Crust., p. 213. 



''A large and valuable species, inhabiting along the borders of 

 rocks, where it is often taken in crab-pots, which, however, its 

 long and unyielding antennae frequently hinder it from entering. 

 Keeping in companies, it also gets entangled in the trammel net, 

 and in some abundance on the fishermen's lines. It meets a 

 ready sale in the market, though not so highly esteemed for the 

 table as the lobster." 



It appears to be more general on our western coasts than else- 

 where. They are rare in the north, both in England and Ireland. 



The young or zoea of this species was first made known by. Mr. 

 p.. Q,. Couch, son of the author of the Cornish Fauna, at the 

 meeting of the British Association at Dublin, 1857.
