II. Description of the Type-Specimen. (Figs. 2 & 3, pp. 396-97.) 

 [Registered number in the Manchester-Museum Collection L. 6271.] 



The animal is well represented by both the intaglio and relievo 



impressions on the re- 

 spective halves of a 

 clay-ironstone nodule, 

 which is roughly circu- 

 cular in shape, unfor- 

 tunately showing the 

 dorsal and not the 

 ventral aspect of the 

 animal. We calculate 

 the length of the whole 

 animal(when extended), 

 from the anterior mar- 

 gin of the carapace to 

 the point of the tail-

have been 

 about 74 millimetres. 

 Some portions appear 

 broader than they really 

 are, owing to the spe- 

 cimen having been 

 crushed. 



Cephalo thorax. — 

 The carapace is sub- 

 quadrate in form, 

 slightly narrower in 

 front than behind. We 

 are unable to make out 

 the character or position 

 of the eyes ; nor can 

 more be said about the 

 carapace, owing to its 

 crushed state. 



Appendages. — 

 Traces of the chelicerae 

 are observed, but are 

 insufficiently preserved 

 to admit of determina- 

 tion. The left second 

 appendage is well pre- 

 served and is long, 

 slender, and chelate, and 

 free from tubercles. 



The hand is long and 

 slender (17 millimetres 

 in length by \ in 

 breadth), and the biting-edge is free from denticulation. The
