254 ZOOPHYTES. 



The Beroe always decreases in size: one of two taken in August, 

 somewhat less than fig. 1, became gradually reduced and enfeebled, until 

 not above a line in length, though still entire, surviving three months in 

 captivity.

§ 2. Beroe punctata. — Plate LIV. Figs. 2, 3. — The nearest resem- 

 blance I have found to this animal is in the work of Eschscholtz, Plate m. 

 fig. 1, b. But I shall not venture to identify it as the same. 



This animal is an inch in length, the lower portion globular; the 

 higher, a large expanding frill, nearly flat. I call this the higher, because 

 it is always above as the animal swims. Eight ciliated ribs traverse the 

 body, which is of a grey colour, and under the ribs there is a reddish 

 tinge. 



Specimens have been taken in March and in August, the largest, 

 which survived a fortnight or longer, in the former.

§ 3. Beroe bilobata, Pl. LIV. Figs. 4, 5, 6, (Eucharis tiedemanni, 

 Eschcholtz). — Although I cannot venture to refer the subjects of this 

 paragraph, and the illustrative figures, to the genus Eucharis of the family 

 Mnemidicp, as instituted by Eschscholtz, there is certainly a considerable 

 correspondence between them. 



The animal represented here doubtless belongs to the genus Beroe. 

 Its form can be more easily recognized from the figures than by descrip- 

 tion, and it is meantime retained under that genus. 



(A.) Eight small specimens were taken accidentally in a jar of sea- 

 water in the month of August. They were rather compressed ovoids, such 

 as might be circumscribed by a circle half an inch in diameter for the 

 largest, but not above a fourth of that for the smallest. The upper part 

 consists of two large lobes considerably asunder, prolonged from the 

 under or ovoidal portion. Four papillous ciliated processes are in the four
