one-third larger. The latero-aaterior border of the former (P. Harveyi) 

 has four spines on each side, whilst P. Broderipii has only two. The 

 orbital regions diSer in form, as well as the markings on the regions of 

 the carapace. 



"We must await more complete materials before attempting a fuller and 

 more careful description ; meantime it is interesting to meet with a spe- 

 cies from so distant a locality which approaches so nearly to our own 

 Gault species P. Broderipii. 



" Formation. — -Cretaceous. Localities. — Hornby Island (No. 2) ; and 

 Comox River, Vancouver Island (No. 3)." 



No. 2 is labelled " N. W. side of Hornby Island, W. Harvey, 1892 " ; 

 and No. 3, "Comox River, at Comox, V. I., C.F. Newcombe, 1892"; but 

 Mr. Harvey says that both were collected on the Puntledge or Comox 

 River, and that the species has not yet been found at Hornby Island. 



A third specimen of the carapace of P. Harveyi, collected on the Comox 

 River by Mr. J. M. Bennett, in 1896, has been presented by him to the 

 Museum of the Survey. It is very similar to the original of figure 17, 

 but has more of the test preserved.

Original description. — " General integument of body extremely thin, or 

 semimembranous, except the first pair of feet, which are protected by a 

 hard covering. Anterior feet (chelipeds) very unequal ; length of larger 

 limb 39 millim. ; breadth 9 millim. ; the dactylus is straight, and is 9 

 millim. long, but the fixed thumb of the propodos is rudimentary and 

 stout, being only half as long as the movable finger. Length of smaller 

 hand about 20 millim. Surface of hands faintly wrinkled.

 ments of the abdomen and of the Fig. is.
