near Port Daniel, in the Baie des Chaleurs. Moreover, it is difficult to 

 see how the specimen thus labelled is to be distinguished from G. sub- 

 gracile, of the same rocks, or from G. septore.

The specimen collected by Mr. Townsend at Durham in 1883, and 

 described on page 41 of the first part of this volume, is still the only ex- 

 ample of this species that the writer has seen.

Hespeler (New Hope), E. Billings, 1857 : an imperfect cast of the in- 

 terior of the shell. This specimen, which is the type of the species, but 

 which has not previously been figured, is represented on Plate 14. In 

 the original description of C Orodes no mention is made of the siphuncle, 

 but it is evidently exogastric and situated close to the margin of the 

 venter. 



Two specimens, which agree with the type of this species in general 

 form, also, very nearly, as far as known, in the relative position of the 

 siphuncle, were collected by Mr. Townsend at Durham between the years 

 1878 and 1882. One of these, the original of fig. 8, on Plate 14, is a 

 well preserved but slightly distorted specimen of the septate portion of 

 the shell, about three inches in maximum length, and with the test pre- 

 served. The surface is nearly smooth, and marked only with very fine 

 and closely disposed transverse strise and a few more distant and a little
