566 MR. G. B. SOWERBY ON NEW SHELLS FROM [DcC. 18, 



specimens brought by Dr. Hungerford, one is less closely ribbed 

 than the others, and is a trifle larger than the type, of which the 

 dimensions are given above ; while the two others are considerably 

 smaller. The spiral sulci on the upper whorls, and on the upper 

 part of the last whorl, are interrupted by the longitudinal ribs, while 

 those towards the base cross them obliquely. The painting consists 

 principally of three broad bands of yellowish buff and brown, and 

 the two larger specimens exhibit a line of the lighter colour inter- 

 rupted by the ribs, situated a little above the middle of the body- 

 whorl.

Long. 37, maj. diam. 13; apert. longa 20, maj. lat. 4 millim. 



Hab. Port Blair, Andaman Island. 



A pretty species of the "Turricula" section, and allied to M. vul- 

 pecula and M. corrugata, but evidently distinct. The three speci- 

 mens collected by Dr. Hungerford are all characterized by a brown 

 belt with a greenish tinge, surmounted by a narrow white band.

Testa oblongo-ovata, utrinque acuminata ; spira parviuscula, acuta ; 

 sufura impressa ; anfractus 7—8, convexi ; liris numerosis sub- 

 nodulosis, lira minore intercurrente spiraliter sculpti, longitudi- 

 naliter inconspicue sulcati, maculis miniitis fuscis, multiseriatim 

 dispositis ornali ; anfractus ultimus subventricosus, fulvo bifas- 

 ciatus, basin versus leviter contractus, haud recurvatus ; apertura 

 mediocriter lata, labrum crenulatum, columella incequaliter sex- 

 plicata. 

 Long. 24, maj. diam. 9 ; apert. longa 1 5, maj. lat. 3g millim. 

 Hab. Port Blair, Andaman Island. 



An exquisite little species of the " Scabricula" section, with a 

 shorter spire than others of the group ; the spiral ridges are 

 numerous and very slightly nodulous, with a very fine (in some 

 cases duplicate) ridge running between. The painting consists of 

 numerous minute brown spots and two rather faint buff bands. 



Pleurotoma notata, n. sp. (Plate XXVIII. fig. 17.) 



Testa elongato-fusiformis, albida, fulvo fuscoque fasciata, strigata
