Anomalina polymorpha, Brady, 1884, FC, p. 676, pi. xcvii, figs. 3-6 (only). 



Anomalina polymorpha, Heron-Allen and Earland, 1915, FKA, p. 712, pi. liii, figs. 2-5. 



Anomalina semi-punctata, Cushman, 1918, etc., FAO, 1931, p. 106, pi. viii, figs, i, 2. 



Three stations: 48; WS 91, 97. 



Only a single typical specimen of Costa's species, as characterized by spinous pro- 

 cesses, was found at 48, and a few young and more doubtful specimens at WS 91 and 97. 



The non-spinous form doubtfully ascribed by Brady (fig. 7) to this species is on the 

 other hand sometimes very common. It appears to have much more in common with 

 A. coronata than with A. polymorph a, and to be identical with Triincatulina vermicitlata, 

 d'Orbigny, which is obviously an Anomalina (see No. 369). 



369. Anomalina vermiculata (d'Orbigny) (Plate XV, figs. 1-15). 



TniiicaUiIiiia vermiculata, d'Orbigny, 1839, FAM, p. 39, pi. vi, figs, i, 2, 3. 

 Anomalina polymorpha, Costa (?), Brady, 1884, FC, p. 6; 6, pi. xcvii, fig. 7. 



Sixteen stations: 48, 388; WS 80, 83, 84, 86, 87, 88, 91, 92, 93, 97, 225, 245, 246, 248. 



D'Orbigny 's figures are very misleading and are probably responsible for the fact that 

 his species, although very abundant in the Falkland area, and probably elsewhere, was 

 never recorded again until 1927, when Cushman (C. 1927, FWCA, p. 177, pi. vi, fig. 11) 

 figured a specimen from the west coast of America under the name of Cibicides vermi- 

 culata (d'Orbigny). His figure shows one view only, but the fact that he assigns his 

 specimen to Cibicides is conclusive evidence that it is not d'Orbigny's species, which is 

 an unquestionable Anomalina. 



The Paris Types are contained in two separate tubes. One marked " lies Malouines " 

 must be disregarded. It contains some depressed, scale-like forms, which could not be 

 identified with either d'Orbigny's description or figures. They probably represent an 

 empirical attempt by some curator to identify unnamed specimens by comparison with 

 d'Orbigny's plate. (It may be noted that d'Orbigny's figures of T. vermiculata are Nos. 

 I, 2 and 3 on plate vi, but are not at the top of the plate where they might be expected, 

 but in the middle. The figures at the top of the plate are of Triincatulina depressa and 

 T. ornata, both depressed species.) The second tube, which is labelled "Amerique 

 meridionale", contains quite typical specimens of a form which is common in our 

 material and deserving of particular notice. 



In 1884, Brady {ut supra) figured a specimen which is undoubtedly d'Orbigny's 

 species, under the name Anomalina polymorpha, Costa (?). His figure differs in many 

 essential points from Costa's species, notably in the complete absence of marginal 

 spines or processes, and in the more or less regularly involute mode of growth assumed 

 by the adult shell. 



D'Orbigny's description of Truncatulina vermiculata is, on the whole, good, and 

 sufficient for the identification of his species when compared with the actual specimens, 

 instead of with his figures. But it is based upon mature specimens, and as the species 

 passes through very dissimilar stages in the course of growth, we supplement it with 

 a full description.
