1 Station. 



A single small individnal at Stn. 1. The range of this species, although wide, is 

 limited, so far as records are available, to the N. Atlantic (where it is frequent off the 

 west and south of Ireland) and to the Pacific. Its occurrence at Kerimba in an 

 entirely new area is noteworthy. 



238. Cassidulina bradyi Norman, var. elongata Sidebottom. (PL L. fig. 20.) 

 Cassidulina bradyi, var. elongata Sidebottom, 1904, etc., RFD. 1905, p. 17, pi. iii. fig. 11. 



3 Stations. 



Single specimens from Stns. 3, 9, and 11. The nature of this little form appears 

 to us to be extremely obscure, and we are inclined to doubt whether it is not more 

 closely related to the genus Balimina, of the group B. convoluta Williamson, than 

 to Cassidulina, but any settlement of this point could only be made by some observer 

 having access to a sufficient supply of material. If a Cassidulina, it is not unlikely 

 tliat the variety may be a depauperate form of the Oassididina described by Goes 

 as "Forma affinis of C. bradyi," and to which he gave the varietal name stenostegica 

 (G. 1894, ASF. p. 44, pi. viii. fig. 427). Our specimen from Stn. 3 was found among 

 the fragments of a large specimen of Cymhalopora hulloides, which had been mounted 

 in balsam and was accidentally crushed by pressure on the cover-glass, and it may 

 perhaps have been ingested by the larger animal. 



We have specimens from Hani 138 of the Scottish Fisheries Cruiser ' Goldseeker,' 

 off Noss Head, Moray Firth, 70 metres, and as Sidebottom's specimens were from 

 Delos, the little organism, whatever its affinities, is widely distributed. 



239. Cassidulina nitidula (Chaster). 



Pulvinulina nitidula Chaster, 1892, CS. p. 66, pi. i. fig. 17. 



Sidebottom, 1904, etc., RFD. 1909, p. 9, pi. iv. fig. 2. 

 Cassidulina nitidula Heron- AUeu & Earlaud, 1913, CI. p. 70, pi. v. figs. 6-9. 



5 Stations. 



A few specimens at Stn. 7 and an occasional one at the otiiers. They are all 

 minute, even for this normally small species, but otherwise distinctive. The occurrence 

 of C. nitidula here in the tropics supports our suggestion [ut supra) as to the wide 

 distribution of the species, the records now ranging from the Arctic Circle to the 

 Equator.
