 is less strongly curved, and the carapace more elongate ; the 

 superficial ornament, morever, is merely striate or finely 

 wrinkled.

Observations. — The above species seems to be represented in 

 collections only by caudal appendages, no example of a carapace 

 having been found directly associated with those remains. A 

 very close analogy exists between our specimens and the above- 

 named species. In connection with the specimens now under 

 consideration it is interesting to note that the late Sir F. 

 McCoy had, many years ago, tentatively labelled them 

 "Leptocheles," but had apparently made no specific comparison, 

 IDresumabl}^ on account of the unpromising appearance of the 

 matrix in which the impressions occur. A wax squeeze taken 

 from these casts in sandstone give surprisingly good results, 

 and even the pittings on the 'sides of the spines can be in this 

 way distinctly made out in two of the specimens. In England 

 C. murchisoni is found in the Ludlow or uppermost Silurian 

 series.
