The specimens from Maud Island and Alliford Bay collected by Dr. 

 G. M. Dawson in 1878 and referred to on page 245 of the third part of 

 this volume, are the only ones known to the writer. In the American 

 Journal of Science for March, 1885, Dr. C. A. White has expressed the 

 opinion that these specimens are more like Gryj^hcea navia, Conrad, than 

 G. Nehrascensis, but the lower valve of G. navia is said to have a narrowly 

 subtrigonal outline, an angular umbo, and a sharp urabonal ridge. 



Anomia Linensis. (N. Sp.) 



Plate 39, fig. 2. 



Upper valve (the only one known to the writer) almost flat, but slightly 

 convex in the umbonal region, subcircular but rather irregular in outline, 

 beak small, flattened obliquely downward, and nearly but not quite 

 marginal. 



Surface marked by numerous closely arranged and slightly flexuous, 

 radiating raised lines or minute ridges, which are crossed and somewhat 

 interrupted by lines of growth and concentric wrinkles. 



Maximum length of one of the best specimens, twenty-seven milli- 

 metres ; greatest breadth practically the same. 



Lina Island, C. F. Newcombe, 1897 : three well preserved moulds of 

 the exterior of upper valves, on a cast of the interior of the shell of 

 Cyprina oecidetdalis. The figure and the foregoing description are taken 

 from a gutta percha impression of one of these moulds. 



Brachiopoda. 

 Terebratula Skidegatensis. (Nom. prov.)

Amended description. — Shell rather large, subovate, broader than long, 

 and broadest at about the midlength, sometimes obtusely pointed in 

 front, when adult, but fully as broad as long when not quite full grown: 

 front margin nearly or quite straight, with no distinct fold or sinus.
