224 PROCEEDINGS OP THE MALACOLOGICAL SOCIETY. 



22. MiTEA (Strigatella) litteeata, Lam. Exceedingly abundant, 

 but not in mucb variety. Very widely distributed throughout the 

 Eastern tropics. 



23. MiTEA (Zierliana) eobtjsta, Reeve. A few, well-marked and 

 characteristic specimens. "We should hardly, like Tryon (Man. Conch., 

 ser. I, vol. iv, p. 157) rank this with M. Woldemarii, Kiener, and 

 M. solidula, Reeve, as a variety of the much rarer and curiously 

 formed M. Ziervogeliana, Gmelin. At all events our experience is 

 that we have never seen intermediate forms. M. robusta is more 

 fusiform than the last-named species, its sculpture finer, and longi- 

 tudinal lirae more frequent, outer lip not so effuse nor incrassate, 

 columella with plicae far less strongly marked. M. Woldemarii, Kiener, 

 a more abundant form, has the outer lip less developed than M. robusta, 

 and the surface of its whorls nearly smooth. The shell is not 

 infrequent throughout the Pacific, and its occurrence in the Andaman 

 Islands shows a northern extension of range that is of great interest. 



24. MiTEA (Tueeicula) EEGiisrA, Shy. One remarkably fine example 

 of what is rightly named the Queen of Mitridse. We have seen 

 examples from the Moluccas and Philippines. 



25. MiTEA (Tueeicula) melongena, Lam. Distribution much the 

 same as the last. 



26. MiTKA (Tueeicula) Geuneei, Reeve. An extremely distinct 

 species, and one of the best defined of the smaller forms of Turricula. 

 We have seen it from the Philippines, collected by the late Mr. Hugh 

 Cuming, and have also met with examples from the Pacific islands. 



27. MiTEA (Costellaeia) ceuentata, Reeve. A subulate form, 

 not typical, of which a considerable series came to hand. Widely 

 distributed in the Eastern tropics. 



28. MiTEA (Costellaeia) dilectissima, n.sp. Eig. II (p. 222). 



Mitra testa fusiformi, albida, spira versus apicem attenuata, solida, 

 gradata, ani'ractibus 9-10, longitudinaliter unclique costatis, costis 

 crassis, Isevibus, nitidis, interstitiis transversim multisulcatis, infra, 

 juxta suturas, ochro-castaneo maculatis, ultimo anfractu versus 

 medium albo-zonato, zona tenuissima, et usque ad basim castaneo, 

 suffuse, apertiu-a angusta, labro simplici, columella recta, quadriplicata. 

 Long. 18, lat. 7 mm. 



Beautiful both in form and coloration. The nearest approach would 

 appear to be If. discoloria, Reeve, from Fiji, New Caledonia (Hadfield), 

 and Solomon Isles (Brazier). This species is usually classed as 

 a Pusia, a section the main characteristics of which are an ovate outline 

 and curt contour of form. Our species differs entirely in its lengthened 

 attenuate whorls, and in a peculiarity of coloration, which we have 

 described above. To recapitulate, the shell is fusiform, white, spire 

 tapering towards the apex, whorls gradate, impressed at the sutures, 

 solid, nine or ten in number, longitudinally costate, the ribs being 

 thick, shining, whitish, smooth, with interstitial transverse deep 

 sulcation. Painted with chestnut-ochre spotting at the interstices, just
