TEXTULARIIDAE

mineral grains appear to be attached directly to the chitinous membrane, often with 

 gaps between the grains. 



These, however, appear to be but trifling differences when compared with the 

 numerous points of agreement, and I should have accepted Lacroix's specific name 

 elegans for our South Georgian specimens, but for the fact that it has been anticipated by 

 Hantken for an entirely different but typical Textidaria, Plecanium elegans (H. 1868, 

 KTF, p. 83, pi. i, fig. 5). This necessitates the abandonment of Lacroix's specific name, 

 and I propose the new name temdssima, which I had already adopted for the South 

 Georgian specimens, as a substitute. 



Textidaria temdssima 



Lacroix {iit supra, fig. 5) figures what is described as the megalospheric form of his 

 species. It is extremely rare, only two specimens having been found. They have no 

 initial spiral and the angle of the sutures is not the same as in his figures of the micro- 

 spheric form (figs. 4, 6). I regard this figure as a distinctive and genuine Textidaria, 

 possibly a new species, but, in any case, unconnected with his microspheric specimens.
