MELVILL : NEW GASTROPODA FROM THE PERSEAN GULF. 8l 



larger rows just below the sutures, and towards the centre of the whorls, 

 and likewise very much expressed in thickness with doubled rows of nodules, 

 at the periphery on the last whorl. At the base, concentrically around the 

 umbilicus are spirally ranged six uniform rows of small nodules. 



I venture to dedicate this species to Mr. W. E. Collinge, as a very slight 

 mark of esteem and appreciation of his unwearied labours in the cause of 

 Malacology. 



vSince descrihing the a'' ove, another specimen has come to hand, from 

 a second station in the Persian Gulf, through the medium of Miss M. Lehour.

An elegant species, its nearest congeners being firstly T.jiainmulata, Kie- 

 ner, from \Vest Africa, which it resembles in its spiral ornamentation, and like- 

 wise, to some degree, in the pale flame-like blotches on, especially the upper, 

 whorls : this is however, a moie delicately moulded shell. And also to T fultoni, 

 Melv., also from the Persian Gulf, it bears a close resemblance, but differs in 

 the more irregular carinations, pale colouration, and the spiral blotches, from 

 its congener, which is always unicolorous white. 



To Mr. Edgar Smith I am indebted for pointing out the salient charac- 

 teristics of this species.

An abnormally whorled and formed shell, most akin, so far as the 

 inhabitants of the Persian Gulf are concerned, to E. (jedrofica, Melv., but 

 the revolute apical whorl is more strongly developed, and the surface per- 

 fectly smooth throughout, with no sign of spiral striation. 'I'he smallest 

 example before me has the mouth in the greater state of perfection, this 

 exhibiting the normal Eulimelloid character.
