CRUSTACEA.

Alauna Bostrata. — Good sir, Edin. New Phil., 1813. 



This animal is probably to be met with in muddy bottoms all 

 around our coast, and along the noithern shores of Europe. 



It was first taken in Cornwall, at St. Ives, by the late Mr. 

 Barlee. From Falmouth I received it trom Mr. Webster. I have 

 taken it among' trawl refuse off Plymouth. 



Genus, Ouma. — Montagu. 



Carapace with the lateral angles produced in front of the con- 

 fluent eye, but not produced into a rostrum like projection. 

 Tail end with two double branched stylets. Telson absent. 

 Cuma scorpioides. — Montagu, Linn. Tram. Vol. ix. 



Cuma Audouinii. — Edwards, Ann. Nat. ; Goodsir ; Edin. New 

 Phil; 1843. 



This animal has not yet been recorded as having been found 

 on the coast of Cornwall, but as it was first found on the south 

 coast of Devon, also in Scotland, I cannot but believe that it 

 must exist on this coast. 



This was taken by Montagu and is the first animal of the whole 

 group that was found. 



Genus, Eudora. — Spence Bate. 

 Differs from Cuma in having the antennEO obsolete. 

 Eudora truncatula. — Spenee Bate, Ann. Nat. Hist., Jnue, 1856.' 

 Plymouth sound.
