90 Rev. A. M. Norman on some Crustacea 



Order CARIDA. 



Genus Crangon, Fabricius. 



Crangon [Cheraphilus) neglectus, G. O. Sars. 



Cheraphilus ner/lectus, G. O. Sars, " Oversi^t af Norges Crustaceer " 

 (Christ. Vidensk. Forhandl.), 1882, p. 45, pi. i. fig. 7. 



Rostrum well rounded at the extremity. Carapace with a 

 single central spine, and a second small tuhercle-lihe spiiie on the 

 central line behind itj without the lobe-like folds oifasciatus, 

 and with the sulcus which in that species defines their lateral 

 regions much less distinct and deep. Antennal scale not 

 greatly widened at the base. Last joints of maxilliped not 

 broadly flattened. Second perajopod longer, reaching one 

 third the length of the hand of first pair ; its chela very weak, 

 the finger and thumb parallel and touching each other, and 

 apparently altogether too feeble to be used for grasping. 

 Body not speckled with brown. Carapace more or less 

 suffused with rufous or chestnut colour ; a band across the 

 fourth segment of pleon, and a second across the telson and 

 uropods of the same colour.

I tooksix specimens of this shrimp, male and female, in 1878, 

 in 3 fathoms water, at Haakelsund, Kors Fiord, West Nor- 

 way, but at the time, from its general resemblance to C.fasci- 

 atus, passed it over as that species, as no doubt Norwegian 

 naturalists had also done. In 1882 it was described by Prof. 

 G. O. Sars. Mr, Scott has now added it to the British fauna, 

 having forwarded to me for examination two or three small 

 specimens which were taken at Tarbert. No other British 

 specimens of this species are in my own collection, but it is 

 not improbable that some of the northern specimens which 

 have been referred to C. fasciatus belong to this new form. 

 The two species to the unaided eye resemble each other 

 closely, and one is apt to be led astray by the circumstance that, 

 like C. fasciatus, C. neglectus commonly has the carapace dark- 

 coloured, and a band of colour across the third segment of the 

 pleon, and another across the telson and uropods ; but the 

 colour of these bands is chestnut (" badia," Sars) mneglectusj 

 but deep umber-brown in fasciatus.
