papillose at the upper end, the papillae merging into the rib. ' The specific 

 name is derived from the Greek W?^*, 'a tower', from the turreted whorls. 

 It may possibly be equally well placed in the genus Mormula, Ad, 

 19, Pyroulina edgarii, n. sp. PI, Fig. 21. 



P. teBta angusta, fusiformi gradatula, tenui, Candida, anfractibus 6, ad 

 suturas impressis, undique longitudinaliter crassicostulatis, costis scalari- 

 formibus, interstitiis trasversim tenuissime striatis, apertura ovata, margine 

 columellari fortiter uniplicato. Long. 2,lat. "75 mm. 



About twenty specimens. This species I venture to name after Mr. Edgar 

 A. Smith, as a very small token of appreciation for his invariable kindness and 

 assistance. The smaller size, turreted or graduate whorls, thick, longitudi- 

 nal, scalariform ribs, and extremely fine transverse striatums, differentiate 

 this little species from Pyrgulina inter striata, Souverbie, and other allies. 



Amongst the Bombay species of this genus, which is sometimes taken as a 

 section of Odostomia, the following occur in more or less plenty : — 



P. callista, Melvill. Twelve of this most beautiful form in the second 

 consignment of shell-sand ; only four in the first. 



P. casta, Adams. A few, not quite typical ; may be a different species. 



P. interstriata,. Souvevhie. I cannot separate the most abundant species at 

 Bombay from this. I have specimens from the Gloyne Collection, from 

 Upolu, precisely similar. 



P. pyrgotnella, n. sp. 



P. edgarii, n . sp. 



20. TURBONILLA ABERCROMBlEI, n.sp. Pi. Fig. 7. 



T. testa pergracili, attenuata, albida, nitida, anfractibus 11-12, subturritis, 

 omnibus longitudinaliter recticostatis, costis interstitiisque seque leevissimis, 

 anfractu apicali in specimine juvenali, heterostropho, vitreo, apertura 

 subquadrata, peristomate simplice. Long. 4, lat. 1 mm. 



Three specimens, of which two are juvenile, showing the apical nucleus, 

 and the third mature, but not quite perfect. Conjecturally, the whorls would 

 be eleven or twelve The longitudinal ribs are straight, the whole surface 

 is very smooth, and the mouth is square. I have much pleasure in associating 

 with this species the name of my friend Mr. Abercrombie, to whose kindness 

 I am indebted for the whole of the material descanted upon in this paper. 



21. TURBONILLA SORORIA, U. Sp. PI. Fig. 17. 



T. testa gracili, attenuata, albido ochracea, semipellucida, tenui, apice 

 heterostropho, anfractibus 11-13, subventricosis, undique longitudinaliter rec- 

 ticostatis, costis, interstitiisque laBvissimis, apertura ovata, peristomate sim- 

 plice* Long. 6 mm. sp. maj., lat. 1 mm. 



Several specimens, in various stages of growth ; the younger shells all 

 showing the mamillate heterostrophe apex so distinguishing a trait of this 

 faiflily. In form resembling T. acuticostata , Jeffreys. - The trivial name now 

 imposed suggests such a'finity.
