Asterolampra (Bishopii). This beautiful form, to which it is impos- PLATE i. 

 sible to do justice in a drawing, is composed_o seven radiates ; the FlG t 

 cellular structure is absent from the rays except in the centre, where

there are a few circular cells, largest in the centre ; margin smooth ; Lat. 47 N. 

 the outer marginal cells are of a deep brown tint and also cellular, ong- 23 

 which shewed the transparent form and radiations of the star very 

 beautifully. 



The drawing may appear stiff and harsh, but it is an exact repre- 

 sentation of this interesting species of Asterolampra. I have named 

 this after my friend George Bishop, Esq., to perpetuate my sense of 

 obligation to him." 



Triceratium ( x (300). -Form triangular ; cells circular, eccentrically Fl - 2 - 

 arranged ; sides concave ; angles neither elevated nor produced, but Lat. 47 'N." S 

 obtuse or rounded ; margin clear. Long. 28' W. 



The forms already known have generally convex sides, acute angles, 

 elevated, cells regularly arranged and extending to the margin, and 

 have been found for the most part in fossil remains. This is probably 

 a variety, differing from those already described by the concavity of 

 its sides, &c., and but one form was detected in all the soundings 

 brought up. 



Entosolenia (?) 



These are separate drawings of different specimens (no doubt of FIGS. 3 A.- 4. 

 the same genus). They are of a pinkish hue, with a clear white canal 

 passing longitudinally and diagonally across the interior ; the lower part 

 of fig. A was dark and spotted ; segments elongated ; arcuate tubes ; 

 porcelainous, opaque, and glossy. 



' This drawing was transferred to ivory by means of the ornamental turning-Lithe, 

 and, without altering or neglecting any of its detail, formed a very handsome and 

 interesting model. Diameter, '21 inches.
