290 Messrs. J. C, Melvill and R. Standen on 
Marjorie, Trichotropis pulcherrima, and the highly sculptured 
and unique Plewrotoma navarchus—are more conspicuous. 
The Scale * are enumerated elsewhere. 
Amongst the “ minutiora ” we would eall especial attention 
to the two new species referred to Homalawxis, the H. cornu- 
Ammonis, especially, being entirely evolute from the apical 
whorl and exactly like a microscopic ‘‘ ram’s-horn.” Cyclo- 
strema euchilopteron, prominulum, and Emarginula undulata 
are very wonderful in their sculpture. A Flucina, the first 
recorded from the Old World, and the curious Rissoina regi- 
stomoides are both noteworthy. So is a new species of Metula 
(M. daphnelloides) and many Pleurotomide, this family ever 
having the pre-eminence in abyssal waters. The Kleznella 
symptesta, also near akin to K. cancellaris and sulcata of 
Adams, belongs to a genus which has not before been known 
to exist in the Arabian Sea or Persian Gulf. 
To Mr. Edgar Smith, I.8.0., and Mr. E. R. Sykes we must 
express our best thanks for assistance, likewise to Mr. G. B. 
Sowerby, and Mr. W. Neville Sturt, of the India Office.
