MONTAGUA MONOCULOIDES. 57 



The first specimen, found by Colonel Montagu and 

 still preserved in the British Museum, is thus rolled up, 

 which circumstance, together with Montagu's incomplete 

 figure in the Linneean Transactions, may account for the 

 circumstance of its so long having escaped the analysis of 

 inquiring carcinologists. We have carefully examined 

 the type in the British Museum, and have no doubt of 

 the correctness of our identification of it with the spe- 

 cimen represented in our figure. We may, however, 

 observe, that the terminal joint of the peduncle of its 

 lower antennas is more decidedly elongated, the spines on 

 the under-edge of its hands stronger, and the two divi- 

 sions of the middle appendages of its tail longer. This 

 specimen was taken from Montagu's favourite hunting- 

 ground, Salcombe Harbour, Devonshire. 



We have also received specimens from the following 

 localities : — Falmouth and Tenby, Mr. Webster. Pen- 

 zance, Mr. Harris and Mr. G. Barlee. Moray Frith, 

 Rev. Mr. Gordon. Skye and Shetland, Mr. Barlee. 

 Plymouth, Mr. Howard Stewart, and C.S.B. Sligo and 

 Belfast Bay, Ireland, Mr. W. Thompson.
