from the Persian Gulf, dec. 141 



A little like P. crocata, Reeve, in form, but in this species 

 the whorls are far more angular and echinate. From P. gas- 

 kelli*, Melv. ( = nr<//ert<i,, Sowb.), it differs in much finer and 

 more frequent spiral liration, the interstices in both species 

 being spirally striate but much finer in character, and as 

 4 to 2 in townsendi compared with gaskclli. General form 

 identical. 



We dedicate this most interesting species to its discoverer, 

 and I am indebted to Mr. G. B. Sowerby for calling my 

 attention to it and confirming my view that it needed 

 description. 



Miira va/tcinatorf, sp. n. (PL IY. fig. 6.) 



M. testa oblongo-fusiformi, solidula, straminea, infra suturas et 

 centraliter floccis albis variegata; anfractibus ad 8, subgradatis, 

 suturaliter vix impressis, undique arctissimo regulariter sulcia 

 spiralibus praeditis, longitudinaliter decussato-cancellatis, ultimo 

 anfractu cseteris magnopere exsequante; aportura angusta, ob- 

 longa, labro paullum effuso, columella quadriplicate, subobliqua. 



Long. 26, lat. 10 mm. 



Hab. Persian Gulf, off Muscat, Arabia. 



I have, in company with the late Mr. Edgar Smith, com- 

 pared this species with its near allies, when we considered 

 that it differed from all others. In size it comes nearest to 

 M. guttata, Svv., and in general appearance is similar to that 

 .species, but the decussate cancellation is here much finer and 

 more regular. Likewise, in guttata the spiral lines are some- 

 what distant. In M. solida, Reeve, found in the region we 

 are treating of by Mr. Townsend, the whorls are more tumid 

 and the sutures deep, [n the larger and coarser M. ambigua 

 and fulva, both of Swainson, the build of the shell is'the 

 same, but the details coarser and cancellation absent. 

 M . jioccata, Rve., is allied in the character of its marking, as 

 its name would imply, but here, again, the somewhat ventri- 

 cose whorls and the sutural arrangements differ.
