Portunus dalyelii. — Spence Bate, Ann. Mat. Mist., 1851, p.

This species was taken first off the coast of Cornwall, by 
Prof. Ed. Porbes and Mr. McAndrews, and afterwards at Pal- 
mouth by Mr. Cocks, and at Penzance by Mr. E. Q. Couch. 
Professor Bell says that it is doubtless the same species as that 
described as P. dahjelii, 1. c. by Spence Bate in the Ann. Nat. Sis. 
for 1851, which he took off the coast of South Wales. But cer- 
tainly the Welsh species is more pronounced in its character 
than the figure given by Prof. BeU.

This species receives its name from the beautifully coloured 
and variegated carapace, which is more conspicuous in the males 
than in the females.

BoU says l.c., p 110. “The occurrence of this crab is ex- 
tremely rare on our coasts. Dr. Leach had only seen one prior 
to the publication of his work, but there is now a fine series in 
the collection of the British Museum.”

Scarce. Bell says that it must be considered as one of the 
rarer species of the Genus. Leach mentions specimens as having 
been taken by Mr. C. Prideaux, in Plymouth Sound, and Mr. 
BeU has had a fine female specimen from the same locaUty. 
It has been found as far north as Skye, and it is recorded 
from Carriekfergus, Dublin Bay, and Cork Harbour, in Ireland, 
and Berwick Bay on the Eastern Coast of England. Mihie
