Long. 3, lat. 1 mm. 



Hab. Persian Gulf, Mussandam, 47 fathoms. 



Of the same character as A. granulata, A. Ad., from the Philippines, but 

 only half the size (3 as against 6 mm.). 



There appears to be a close connexion between certain of this genus and 

 some included at present in Miralda, A. Ad. It is often hard to draw any 

 precise lines of demarcation between these genera. 



ACTjEPYRAMIS BREVICULA, sp. n. (PI. C. fig. 4.) 



A. testa minutissima, abbreviata, alba, compressiuseula, solida ; anfractibus 



quatuor, quorum apicalis heterostrophus, vitreus, laevis, cseteris suturis 



gradatulis, longitudinaliter crassicostulatis, spiraliter undique rudiliratis ; 



apertura ovata, apud basim paullum incrassata ; columella uniplicata. 

 Long. l - 75, lat. 1 mm. 



Hab. Persian Gulf, Sheikh Shuaib I., 15 fathoms. 



Very minute, but characterized by its compressed abbreviate form and rude 

 ssulpture, the whorls all gradately angled at the upper part. The figure 

 hardly shows the ribs sufficiently prominently, and there is no decussation or 

 granulation to speak of. 



PYRGULINA MANORS (Melv.). (PI. C. fig. 5.) 



Turbonilla (Pyrgostelis) manorce, Melv. Mem. Manch. Soc. vol. xliii. (1898.) 

 no. 4, p. 23, pi. i., fig. 22. 



Hab. Gulf of Oman, lat. 24° 58' N., long. 56° 54' E., 156 fathoms. 



We have caused this species to be again figured on a highly magnified scale, 

 the result being to decide us that it should be considered a Pyrgulina, allied to 

 Edgarii, Melv., and interstriata, Souv., in spite of the apparent absence of 

 the columellar plait. The original specimens came from off Manora Point, 

 Karachi, where they were plentifully dredged at a slight depth by Mr. 

 Townsend. 



SCALA (CONSTANTIA) INTERTEXTA, sp. n. (PI. C. fig. 6.) 

 M testa gracili, fusiformi, albida, delicata ; anfractibus 10, quorum apicales 

 tres parvi, vitrei, laeves, cylindrici, caeteris ad suturas multum impressis 

 pulcherrime regulariter decussatis, ad juncturas lirarum spiralium cum costulis 

 fimbriolatis, ultimo anfractupaullum prolongato ; apertura obliquiovata 

 labro effuso ; columella paullum incrassata, simpliei. 

 Ann. & Mag. N. Hist. Ser. 7, Vol. xii. 

 Long. 7, lat. 1*75 mm. 



Hab. Gulf of Oman, lat. 24° 58' N., long. 56° 54' E., 156 fathoms. 

 Rarely has a small mollusk caused such perplexity as in the present instance. 

 Two examples alone have occurred, but both have the apex perfect, this being 

 non-heterostrophe, though in most other particulars the form and texture re- 

 call such pyramidelloid genera as Mormida, Pyrgulina or Mumiola, especially 

 one species of the latter genus — M, spirata, A. Ad. — which also occurs in the 

 same seas.
