TORNATELLINA. 183 



Damley Island, Torres Straits (Chevert Exped.). Also 

 northeastern Queensland and islands between there and New 

 Guinea. 



Tornatellina mastersi BRAZ., Proc. Linn. Soc. N. S. Wales, 

 i, 1876, p. 108. HEDLEY, P. L. S. N. S.~W., xxvi, 1901, p. 705, 

 pi. 34, f. 13, 14. 



"This species is of a very dull color, more so than any of 

 the other species described in this paper. Eighteen speci- 

 mens found on a tree at 600 feet elevation, the highest part 

 of the island" (Brazier). 



Mr. Charles Hedley, whose figure of the type is copied on 

 plate 38, writes as follows: 



"One of the types from Darnley Island, 2.9 mm. in length, 

 is shown at h'g. 14 [8]. An example of T. petterdi Brazier 

 (op. cit., p. 109) from no. iii, Barnard Islands, 2.7 mm. long, 

 is represented by fig. 13 [pi. 38, fig. 9] . It seems to me an im- 

 mature state of the same species. T. grenvillei Brazier (op. 

 cit., p. 109) appears from a study of the types also to be iden- 

 tical with T. mastersi. To this species belongs also a Torna- 

 tellina from Boyne Island and Warroo, Queensland, identi- 

 fied as T. cucharis by Hedley and Musson these Proceedings 

 [Linnean Society of N. S. Wales] (2), vi, 1892, p. 558, pi. 28. 



4 ' The double twist on the columella distinguishes this from 

 the very similar T. oblong a Pease, of the Central Pacific. T. 

 jacksonensis Cox, is a more slender shell" (Hedley). 



In a series from Somerset, Cape York, the largest shell 

 measures 3.6x1.9 mm., with 5*4 whorls (pi. 53, fig. 11). 

 Others are smaller, and resemble Mr. Hedley ? s figures in con- 

 tour. The columella has two small and very oblique folds, 

 which in the young are hardly noticeable in a front view. 

 Parietal lamella about one-third of a whorl long, very low 

 and slender. It is smaller in the neanic stage than in the 

 adult. 



The original descriptions of the forms regarded as syn- 

 onyms here follow.
