174 "TERRA NOVA" EXPEDITION. 



At Station 2. the large specimen shows spu-al arrangement of the early 

 portion of the shell and is referable, under extreme taxonomical stress, to Lingu- 

 linopsis carlofortensis, Bornemann (B.. 1883, L. p. 26, pi. vi). As we have already 

 indicated elsewhere (H., 1919, BMB. p. 81), we regard the subgenus Lingulinopsis as 

 unworthy of retention, and we record this specimen merely as a biological variation 

 from the type.

Station 55. 



A single typical example from the southernmost Station. This species has only 

 been recorded hitherto from the West of Ireland, Scotland (several " Goldseeker " 

 dredgmgs), and the Estuarme Clays of Magheramorne.

Very rare, recent in the N.Z. area at Station 2, fossil at Station (1. very 

 small but typical examples at Station 31.

Frotidicularia pyfjmaea, Sidebottom, 1904, etc., RFD. 1907. p. .5, pi. i, fig. 27. 



Heron-Allen and Earland. 1913, 01, p, 96, ])1. viii, fig, 14, 



Station 27. 



A single specimen which, to obviate the erection of a new species on such 

 insufficient evidence, we attribute to Sidebottom's species, although it is not in 

 strict agreement with that, or with F. denticulo-carinata, Chapman, another species 

 to which it bears some features of resemblance (C, 1891, etc., GF. 1894, p. 155, 

 pi. iii, fig. 4). The specimen is perfect. 31 nnn. long, hyalme, consisting of four 

 chaml^ers only, exhibiting little increase in size. The primordial chamber is 

 carinate. The second is carina te in the lower portion and furnished with pro- 

 jecting recurved hooks which extend from the limbate marginal edge of the 

 chamber. In the third and fourth chambers, although the marginal edges are 

 limbate and projecting, they do not form hooks. The sutural lines are depressed 

 and only slightly curved, and the specimen might l^e referred to either Lingulina 

 or Frondicularia.
