 GASTEEOPODA. 



Pleurotosiaria Skidegatensis, Whiteuves. 



Ph'urotomaria Skidegatensis. — 1876. Tliis volume, p. 51, pi. 9, figs. 6 and 6a. 



Soiith side of Maud Island : one imperfect and badly preserved but 

 characteristic specimen. 



Cinulia. (Species Undeterminable.) 



South side of Maud Island : a cast of the body whorl and part of the 

 preceding volution of a subcylindrical and apparently undescribed 

 species with a rather long spire. Very similar specimens, which pro- 

 bably belong to the same species, were collected in the Lower Shales 

 of Skidegate Inlet by Mr. James Eichardson in 18*72. 



LAMBLLIBEANCHIATA. 



Pleuromya subcompressa, Meek, var. laevigata. 



Plate 33, fig 3. 

 For the synonymy of this shell see page 222. 



South side of Maud Island, one very j)erfect and undistorted cast and 

 a fi-agment of another. The best specimen from this locality differs a 

 little from the smooth forms of P. subcompressa collected from the 

 Lower Shales of Alliford Bay and described on page 224, in being pro- 

 portionately broader in the direction of their height and in not being so 

 angular on the anterior and posterior umbonal slopes. 



A precisely similar example to the one from Maud Island was 

 collected by Mr. G. M. Dawson at the Iltasyouco Eiver in ISTG. 



Cardium tumiduluji. (N. Sp.) 



Plate 33, fig. 4. 



Shell extremely small for the genus, strongly convex and very tumid 

 in the middle, obliquely compressed at the sides, especially above : 

 greatest thickness through the closed valves about equal to their maxi-
