" These specimens are \ ery distinct, but without more materials I should 

 not feel justified in separating them generically. I prefer rather to place 

 them in Bell's genus Plagiolophus, which was proposed to receive P. 

 Wetherelli, from the London Clay of Sheppey. 



" The same species — described under the name of GlyphitJiyreus affinis 

 (Reuss) — was figured and described by Reuss nearly at the same date. 

 Reuss also adds another species, Ulyphitltyreus Jormosits, Reuss, from the 

 Upper Cretaceous of Mecklenburg. 



'' I feel satisfied to leave these Vancouver Island crabs in this genus, and 

 to designate them by the trivial name of vancoitvere^isis. 



'• Two specimens were collected on the north-western side of Hornby 

 Island, and one on Comox River, Vancouver Island, British Columbia. 

 The locality of the Geological Society's specimen is not marked, but it is 

 from Vancouver Island. 



" Nos. 3 and 4, from Hornby Island, belong to the Provincial Museum 

 of Victoria, Vancouver Island. 



" No. "2 specimen shows traces of limbs, and the flattened propodos of a 

 chelate fore-arm 13 millim. long x 8 millim. broad." 



The thr; e specimens forwarded by the writer were collected by Mr. 

 Walter Harvey, who says that he got one specimen of this species on the 

 Puntledge or Comox River, at Comox, V.I., in 1891, several at Hornby 

 Island in 1892, 1893 and 1896, and a few at Denman Island in 1892 and 

 1893. One of the specimens collected by Mr. Harvey at Hornby Island 

 in 1896, and now in the Museum of the Survey, has almost the whole of 

 the ten walking legs preserved.

The following is the original description of this species, but the num- 

 ber of the figure is altered to suit this publication. 



"Genus Pal.eocorystes, Bell. 



" In this genus the carapace is longer than broad, flattish, becoming nar- 

 rower gradually towards the posterior border, rostrum short, latero-ante- 

 rior border dentated. Orbits moderately broad, with two fissures. 



" The carapace in all the species of this genus at present known is simi- 

 lar to that of the masked crab, Corystes^ now living on our English coasts.
