456 COROPHlIDiE. 



form of a long point or process as shown at *. The first 

 pair of legs have the hand and wrist continuously oval. 

 The second pair have the wrist as broad again and much 

 longer than the hand, the subapical process is double- 

 pointed ; the hand has the inferior margin irregularly 

 waved, but running subparallel with the superior. The 

 finger is lanceolate, but slightly curved, and sparingly 

 fringed with hairs. The first three pairs of legs are 

 shorter than the last two, the thighs being equally 

 dilated. The posterior pair of caudal appendages are 

 very robust ; the short single branch is tipped with 

 short, slightly-curved, obtuse spines, the middle tail-piece 

 having several rows of minute sharp teeth upon each 

 lobe. The colour of the animal is pale yellow or horny, 

 slightly studded with black spots. 



We took our first British specimens in Oxwich Bay, 

 on the coast of South Wales, and have since taken it in 

 Plymouth Sound, in company with the late Mr. Howard 

 Stewart. The Rev. A. M. Norman has sent it to us 

 from the coast of Northumberland ; but the original 

 specimen of the species was taken by Mr. Templeton in 

 the Atlantic Ocean, 



Dana describes, under the name of Pyctilus Brasiliensis, 

 a specimen which agrees with our British form ; and 

 it is not impossible, since Templeton's sea voyage was 

 from the southern to the northern hemisphere, that his 

 species may have been taken off the coast of Brazil, and 

 therefore identical with Dana's species; at all events 

 this forms another evidence of the great resemblance 

 between the British and South American Crustacea. 



We have never taken this species within its abode ; 

 but Templeton figures the cell in the form of a long, 

 narrow, membraneous tube, about one-fifth of an inch 

 in length, his specimen being about one-eighth.
