A single specimen which we figure from Stu. 6 presents the essential characteristics 

 of this species in its flat superior face, conical inferior face, and strongly limbate sutural 

 lines, but it has only seven chambers in the final whorl, each chamber being considerably 

 longer than is the case in the large tropical specimens on which the species was founded. 

 The occurrence of a specimen in a British gathering is very startling, the records of 

 the species being confined to tropical shallow water, where it attains a very large size. 

 It may, of course, be nothing more than a local " sport " from R. beccarii ; but, if so, its 

 assimilation of the characteristics of another typical species is equally remarkable. 



Parker and Jones's species appears to be merely a compressed and broadened form of 

 the Gyroidina conoides of d'Orbigny (d'O. 1826, TMC. p. 278. No. 9), of which we have 

 examined the type-specimens both at Paris and at La Rochelle.

Almost universally distributed and varying greatly in abundance. Commonest 

 at Stns. 8, 12, and 16. At Stns. 17 and 23 a very thin scale-like form, with fine 

 perforations ; both free and attached. At Stn. 4 one large double specimen, resulting 

 from the fusion of two individuals at a comparatively advanced stage of growth. 



306. Gypsina vesicularis (Parker & Jones). 



Orbitolina vesicularis, Parker & Jones, 1859, etc., NF. 1860, p. 31. No. 5. 

 Gypsina vesicularis, Brady, 1884, FC. p. 718, pi. ci. figs. 9-12. 



5 Stations. 



Only an occasional specimen, except at Stn. 3, where many of all sizes were found, 

 including a number of hollow specimens such as we figured from Clare Island (H.-A. & 

 E. 1913, CI. pi. xiii. fig. 11). 



307. Gypsina globulus (Reuss). 



Ceriopora globulus, Reuss, 1847, Haidinger's Naturw. Abh. Wien, vol. ii. p. 33, pi. v. fig. 7. 

 Gypsina globulus, Brady, 1884, FC. p. 717, pi. ci. fig. 8. 



3 Stations. 



Very rare. The specimens are quite typical, both large and small.
