﻿Medusce and Ctenophores from Firth of Forth. 311 



27th June, 2nd July, and 11th July, being quite numerous 

 on the last two dates, and of various sizes from f of an inch 

 to as much as 4J inches (2-3 on the average) in length. 

 Some were shedding ova. During December (12th, 14th, 

 and 23rd) Bero'e was also abundant in Burntisland Harbour, 

 the length ranging from about 1 inch to 3^ inches. Colour 

 pale pink. 



In this area the specific names ovata and cucumis have 

 doubtless been applied to the same form, but it would seem 

 that they really represent two different species. In B. 

 cucumis, Fab., according to Chun (I.e.), the proliferations of 

 the meridional vessels which are situated on the stomach- 

 wall, are not in communication with the stomach vessels, 

 while they are in B. ovata, Bosc, from the Mediterranean. 

 Our specimens conform in this as well as in other respects 

 to the description of B. cucumis. 



Note. — Besides a series of preserved specimens of the 

 species mentioned in the paper, there were exhibited at the 

 meeting living examples of Tima bairdii, Aequorea norvegieUj 

 Bolina infundibidum, and Bero'e cucumis captured at Burnt- 

 island that day.
