Spirorhis cancellata is in point of ornament the prince of our 

 Spirorbes. It is thick, regularly spiral when young, but with the 

 mouth tending upward when old. Above, it has two, or, in old 

 shells, three strong ridges revolving with the whorls, and giving it 

 an elegant fluted appearance, and the outer side presents a furrow 

 crossed by strong transverse bars, or in other shells appears as a 

 regular slope wilh a series of depressed spaces at regular intervals. 

 The whole appearance of this shell in a perfect specimen is very 

 elegant, and as I have not been able to find a good figure of it in 

 any work that I have consulted, I have attempted to represent it in 

 the figures on this page. It is a reversed species. S. cancellata 

 abounds in Mr. Bell's Gasp^ collection. It is one of the species 

 found by Fabricius in Greenland and named by him, but I am 

 not aware that it has been met with since, until dredged by Mr. 

 Bell in about 60 fathoms on the Gaspe coast, where it lives 

 attached to the valves of dead shells. It is also in Mr. Carpen- 

 ter's collection from Labrador. 



Sinrorhis granulata^ (Muller) resembles that last described, but 

 wants the ornament around the margin, having only two furrow 

 and three sharp elevated ridges on the upper side, and it is not 

 reversed. Fabricius, who found it in Greenland, states that its 

 animal is yellow, with a white stopper on a short stalk, and sis 

 respiratory filaments. It occurs, though rarely, in Mr. Carpenter's
