228 CRETACEOUS PODOPHTHALMATA. [May 1 896, 



-- The- same species — described under the name of GlypTiithyreus 

 affinis (Eeuss) — was figured and described by Eeuss nearly at the 

 same date. Eeuss also adds another species, OlypJdihyreus for- 

 mosus, Eeuss, from the Upper Cretaceous of Mecklenburg. 



I feel satisfied to leave these Yancouver Island crabs in this 

 genus, and to designate them by the trivial name of Vancouver ensis. 



Two specimens were collected on the north-western side of 

 Hornby Island, and one on Comox Eiver, Yancouver Island, British 

 Columbia. The locality of the Geological Society's specimen is not 

 marked, but it is from Yancouver Island. 



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

 Museum of Yictoria, Yancouver Island. 



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

 of a chelate fore-arm 13 milliin. long x 8 millim. broad.
