HopiiOPARiA Westoni, sp. iiov. (PL XVII, Figs, la, b, c.) 



AMONG other specimens received from the Geological Sui-vey 

 of Canada are the fragmentary remains of a Crustacean 

 (enumerated in Dr. Whiteaves' list as No. 10), comprising the 

 X)j abdomen (a), a small part of a carapace (b), and the penultimate 

 ^' joint of one of the chelate fore-limbs (c), occurring in detached frag- 

 ments (probably parts of a concretionary nodule). They are labelled 

 Ked Deer River, Alberta Range 15, Township 23, west of the 4th 

 principal meridian; collected by Mr. T. C. Weston, 1889. Although 

 in so fragmentary a condition these specimens are of much interest, 

 and are characteristic in their details. 



The abdominal segments are united and display the characteristic 

 markings and raised ridges on the segments seen in the living 

 Nephrops Norvegicus and in Hoploparia Saxbyi and other English 

 Cretaceous forms. The epimeral portions of each segment are roundly 

 falcate, and divided from the tergum by a well-marked ridge. The 

 sixth segment and the telson are more rugose and marked by parallel 

 ridges. The cephalothoracic portion is too obscure for description ; 

 the surface is tuberculated. The penultimate joint of the great 

 claw is very coarsely and strongly tuberculated, as much so as in 

 JSnoplodytia and in Moploparia scabra. 



Length of abdomen (measured along dorsal line), 6| inches ; 

 width over third segment, 2^ inches. Length of penultimate 

 segment of great claw, 2^ inches ; breadth, 2 inches. 



I have designated this form as Hoploparia Westoni, after the 

 discoverer. The specimen is from the Upper Cretaceous of the 

 North- West Territories. 



Hoploparia Bennetti, sp. no v. 



This species is based on a very imperfectly preserved specimen, 

 No. 6 in list, contained in a dark nodule (measuring 5" x 2") split
