raliter crenato-striatis. — Length ^ths of an inch; breadth j^th 



of an inch. PI. IX. fig. 3. 



Exactly resembling a Fusus corneus in miniature, but evi- 

 dently a full-gi'own shell, and well-characterized by its peculiar 

 sculpture. No described species of Fusus can be confounded 

 with it. We dredged it in fifty fathoms between Fair Isle and 

 Fitful Head. On showing the specimen to Mr. Jeffreys, he re- 

 cognized it as the F. albus of his manuscripts *. 



6. Astarte crehricostata, sp. nov. PI. IX. fig. 4. 



We have applied this name provisionally to a remarkable 

 Astarte of which several single valves, not very fresh, were 

 dredged up on the west coast of Zetland. They evidently be- 

 long to a species very distinct from any European form with 

 which we are acquainted. These valves are ovate, oblique, very 

 depressed, with numerous (thirty), very prominent, narrow, ele- 

 vated, regular, transverse ridges which become obsolete ante- 

 riorly, where they are interspersed by slightly oblique striae. The 

 margin is crenate. The largest valve measures 1 inch y%ths in 

 length and the same across. 



7. Astarte horealis. 



We dredged in fifty fathoms water on the Ling Bank off the 

 west coast of Zetland a valve of this well-known species, so 

 fresh that we cannot doubt that it is a living inhabitant of our 

 northern seas.

Subfam. Gourin^, Ground Pig eom. 



The great series of ground pigeons and ground doves presents a 

 marked gradation in form and character from genera allied (ex- 

 cepting in the form of the feet) to the Caiyophagce and Ptilino- 

 podes of the preceding subfamily, to others which exhibit a nearer 

 relationship to the species of the next subfamily. The size also 

 varies remarkably, as both the largest and smallest pigeons 

 known are comprised in this group ; some attaining the magni- 

 tude of a hen-turkey, while others are scarcely bigger than a 

 sparrow. These birds are of a shorter, more full, and grouse- 

 like figure than that of other pigeons, having the wings more or
