Calocaris baknardi, n. sp. 

 Plate LXVI. 



From Bell's C.macanclreae the Tpvesent species is well distinguished 

 by the very different proportions of the large chelae in the first 

 peraeopods, the fingers in the former being about three times as long 

 as the palm, while here the fixed finger is not longer than the palm 

 and the movable finger about once and a half as long as that shorter 

 part of the palm to which it is attached. In C. alcocki, McArdle, 

 the palm is as long as the fingers, but the whole structure is more 

 slender than in the new species. There also the rostrum is 

 upturned, whereas here it is perfectly straight and horizontal ; 

 the carinae diverging backwards from the rostrum are each sur- 

 mounted by three denticles. The telson has a minute median spine 

 in its very shallow apical emargination. 



The eyes are large, flattened, and as preserved opaque white.
