reduced to working order, they should never be neglected. The 

 tray of earth will be found to equalise the temperature wonder- 

 fully, preventing too sudden an accession when the reservoir is 

 filled, and retarding its decrease afterwards ; if it falls very low, 

 a blanket may be spread over the snakes as they lie upon the 

 gravel, but, as we have seen before and shall see again, it is not 

 altogether undesirable that the heat shall be lessened at times.

NOTES AND OBSERVATIONS ON BRITISH 

 STALK- EYED CRUSTACEA. 



By John T. Carrington, F.L.S., and Edwakd Lovett. 

 (Continued from vol. vi., p. 391.) 



Pagurus ferrugineus, Norman. 

 This small crab appears to partake of the features of 

 P. Hyndmanhi and P. Levis, for its large claw is reddish in colour, 

 slightly hairy above, hut smooth beneath ; its remaining legs are 

 banded red and white. It has been recorded from Shetland, 

 Northumberland, the Clyde, and Guernsey; and we have obtained 

 it from the last-named locality. 



Pagurus Forbesii, Bell. 



This species was described from a single specimen sent to 

 Prof. Bell by Mr.. Corks, of Falmouth. The carapace is smooth ; 

 antennae longer than the first pair of legs ; eye-stalks club-shaped, 

 and as long as the first joint of the inner antennas. Anterior 

 feet on the unequal wrist and hand roughly granulate, the second 

 and third pairs slightly compressed and with numerous small 

 reddish brown spots. 



This species, we observe, has been recorded from Galway 

 (rare), and off the South Isle of Arran, in sixty fathoms. 



Pagurus Dilwynnii, Bate. 



The striking peculiarity of this crab is that its left claw, 



and not its right, is the larger. The colour is of a bluish brown 



in life, which, however, is lost after death. The second and third 



joints of the anterior legs are toothed and armed with a medial
