262 GAMMA RID JS. 



second pair are large, having the hand broad, truncate ; 

 the palm being at nearly right angles with the inferior 

 margin, and furnished near the inferior angle with several 

 strong short hair-like spines. The finger is arched. The 

 walking legs are all nearly of the same length, the three 

 posterior pairs being very broad. The last two pairs of 

 caudal appendages have the branches unequal in length, 

 the last pair not reaching beyond the extremity of the 

 preceding. The terminal caudal plate is short and 

 ovately lanceolate. 



We received this species first from Mr. Edward, of 

 Banff, from which specimen the original description in the 

 Catalogue of the British Museum was drawn up. In the 

 description, as well as in the figure accompanying it, the 

 antennas are represented of the same length ; but a con- 

 siderable number of specimens sent to us by the Rev. 

 A. M. Norman, from the coast of Yorkshire, have the 

 antennas invariably unequal in length. We have, there- 

 fore, considered the specimen from Banff as having been 

 damaged or an accidentally altered form, and regard the 

 Yorkshire specimens as typical of the species. We have 

 also received it from the Shetlands from Mr. Norman. The 

 late Dr. G. Johnson also sent us a number of specimens 

 from Berwick Bay. The colours of the specimens from 

 the Shetlands were of a dark orange, striped with 

 brownish red ; each band corresponding with the 

 posterior margin of each segment of the animal. 



This and the following species are named in honour of 

 the two great northern heroes whose history has come 

 down to us so dimly through the vista of time.
