"Original specimens" (figs. 18 and 19) "preserved in concretionary 

 nodules of Cretaceous age from Comox River, Vancouver Island. Col- 

 lected by Dr. C. F. jSTewcombe (1892). Museum of tlie Geological Survey 

 of Canada, Ottawa. 



" A nodule from Vancouver Island, in the Geological Society's Museum, 

 contains the remains of the large hands of Callianassa Whiteavesii. A 

 second nodule from the same collection contains the carapace of Plagio- 

 lopJius vancouverensis " (Woodward). 



Remains of one or possibly two individuals, that Dr. Woodward has 

 since identified with this species, had previously been collected on the 

 Puntledge or Comox River, near Comox, by the Rev. G. W. Taylor in 

 1889, and are now in the Museum of the Survey. Specimens collected 

 at Hornby and Denman islands by Mr. Harvey in 1892 or 1893, that 

 are probably referable to this species, have been loaned to the writer by 

 the authorities of the Provincial Museum at V^ictoria, B.C. Dr. Wood- 

 ward also identifies with C. Whiteavesii, several " well-preserved, flattened 

 chelate hands" collected at Sounding Creek (in the north-west corner of 

 the District of Assiniboia), by Mr. J. B. Tyrrell, in 1886, but these are 

 from the Pierre-Fox Hills or Montana formation, of the country east of 

 the mountains.

Original description. — "This species is based on a very imperfectly 

 preserved specimen, Xo. 5 in list, contained in a dark nodule (measuring 

 5" X 2 ") split in halves very irregularly, and exposing the dorsal aspect of 

 five posterior abdominal somites and the telson with two swimmerets on 

 the left side still attached. The abdominal segments are smooth, and the 

 epimera broadly falcate and pointed as in Homarus. Length of five 

 abdominal segments, 40 mm.; length of telson, 13 mm.; breadth of
