222 DR. H. WOODWARD ON CRETACEOUS PODOPHTHALMATA [May 1 896, 



Those from Nanaimo, Comox, or Yaldez Inlet are :— 



Inoceramus texanus, Conrad. 



nebrascensis, Owen. 



undtrtatoplicatus, Eoemer. 



confertim annulatus, Eoemer. 



In 1861 Mr. Meek (Proc. Acad. Nat. Sci. Philad. vol. xiii. p. 314) 

 added to the list of Cretaceous fossils from Vancouver ^ Dosinia 

 tenuis, from Nanaimo ; Inoceramus subundatus, Baculites occidentalism 

 Ammonites vancouverensis, and Nautilus OampbeUi, from Comox; 

 Ammonites complexus, var. suciensis, from Comox and the bucia 

 Islands ; and Baculites inornatus, from the Sucia Islands. 



In 1864 Mr. W. Gahh, in vol. i. of the < Palaeontology ^ of Cali- 

 fornia,' described and figured two new species of fossil shells, 

 namely : — Hamites vancouverensis and Pecten Traskii from Kanaimo. 



For an admirable summary of our knowledge of ' the Cretaceous 

 System of Canada,' see the Presidential Address to the Royal Society 

 of Canada by J. F. Whiteaves, Section iv., May 23rd, 1893, pp. 3- 

 19 (Trans. Roy. Soc. Canada). 



I find that it is impossible here to give a full list of all the fossils 

 obtained from these beds, and I have omitted the fossils of the 

 upper series of deposits entirely, as also the plant-remains. 



Besides the mollusca, a decapod crustacean (named but not 

 described as Hoploparia or Podocrastes ? didmenensis) has been 

 recorded from the Niobrara-Benton group of Manitoba — a long- 

 tailed decapod (Palceastacus) from the Pierre Fox Hills or Montana 

 formation, and a beetle, Hylohites cretaceus, Scudder, from the Pierre 

 Shales, Millwood, Manitoba. 



The species of Crustacea now to be noticed comprise : — 



1. Several examples of a small macrurous decapod belonging to 

 the genus Callianassa, met with very frequently in the Faxoe Beds, 

 the Maestricht Chalk, the Greensand of Colin Glen, Belfast : 1 and 

 also from lower beds (C. isochela), 2 Kimeridge Clay of the Sub- 

 wealden boring ; and from higher and later ones, namely, Callia- 

 nassa Batei, 3 Upper Marine Series, Hempstead, Isle of Wight. 



This is a small burrowing crustacean, and is found living at the 

 present day; usually only the chelae are obtained in dredging, 

 owing to the animal lying in its burrow, and the hands alone pro- 

 truding from the aperture. 



The body- (thoracio-abdominal) segments are nearly soft, owing 

 to the animal's constant habit of lying concealed, only the hands 

 having a hardened calcareous covering.
