 This fine species is distinguished from U. treimdma, its 

 nearest ally, first, in the aperture being stained with deep 

 red, secondly, in being mostly rather swollen posteriorly 

 beyond the middle, and, thirdly, in exhibiting a greater 

 variety of colouring in the painting. At Fig. a, y, the 

 painting is simply purple-lake upon a white ground. At 

 Fig. b the ground is camelion, and the painting is of 

 purple-lake shaded with a rich golden yellow. Kig. <• 

 represents a very richly pamted dark olive-brown, blue- 

 shaded upon a camelion ground. At Fig. d the streaks 

 are of a milky blue-green shaded with the same golden 

 yellow as in the purple variety b. Fig. e is a variety very 

 richly painted with dark in miscellaneous angidar blotches, 

 neither streaked, nor disposed in bands ; and Fig./ is 

 almost an uninterrupted brown, obscurely banded. These 

 figures illustrate only a kw of the most striking varieties 

 of this beautiful species, which might be i;onsiderably 

 added to if space permitted.
