DECAPODA— BRACHYURA— CALLIANASSIDiE. 



CALLIANASSA, Leach, 1814. 



€allianassa Whiteavesii, H. W., 1896. (PI. XVII, Figs. 2a, h.)

In addition to the Macronran Decapods already noticed as received 

 from Dr. J. F. Whiteaves, F.G.S., ou behalf of the Geological Survey 

 of Canada, I find the following: — 



No. 2. Nodule in four pieces collected by the Eev. G. W. Taylor 

 on the Puntledge or Comox Kiver, Vancouver Island, in 1889. 



The four parts of this nodule display on the split surfaces the 

 remains of a CalUanassa, or possibly parts of two individuals, but so 

 broken up and detached as to be difficult to describe. The large 

 fore-limbs are seen (in parts), and the smaller limbs and segments of 

 the abdomen are also present, but in a very fragmentary state. These, 

 no doubt, are referable to one and the same species, viz. CalUanassa 

 Whiteavesii (see Q.J.G.S., 1896, vol. lii, p. 223, figs. 1, 2). 



Formation : Upper Cretaceous. 



Locality : Comox Eiver, Vancouver Island, 



No. 11. Eight portions of nodules (a and b, c and d being 

 counterparts; e and / are halves of distinct nodules; g and h are 

 pieces of the rock itself, not nodules), a and b, c and d, e and / 

 display the well-preserved flattened chelate hands of CalUanassa 

 Whiteavesii (PI. XVII, Figs. 2a, b) ; g contains a fragment of a 

 hand ; h is not a Crustacean fragment, but an undoubted fish-bone. 



All these specimens are from the North-West Territory, Town- 

 ship 30, Range 8, west of 4th principal meridian, and were collected 

 by Mr. J. B. Tyrrell, F.G.S. (May 25th, 1886). 



Note on North American Cretaceous Species of CalUanassa. 

 Dr. J. F. Whiteaves calls my attention to a paper by Mr. W. M. 

 Gabb in the Geological Survey of California, vol. i, Palasontology 

 (1864, 4to), Section iv. Description of the Cretaceous Fossils, 

 p. 57, pi. ix, figs, la, 6, c. Here Mr. Gabb describes and figures 

 three small Crustacean fragments, under the name of CalUanassa 

 Stimpsoni, from Chico Creek and Clayton Contra Costa County, and 

 also found near Canada de las Uvas from both divisions of the 

 Californian Cretaceous. PI. ix, fig. la, is correctly described as three 

 segments of abdomen, and may very likely belong to a CalUanassa, 

 but figs, lb and c are pieces of an ornamented chela and do not agree 

 with any known CalUanassa. CalUanassa Stimpsoni may therefore 

 properly remain on the list represented by fig. la, but the other 

 figures do not belong to the same Crustacean, and should be 

 separated fi-om it in future. The chela may even have belonged 

 to a Brachyuran decapod.
