new Gastropoda from the Persian Gulf, ke. 305 
Acteopyramis letitia*, sp.n. (Pl. XAT. fig. 3.) 
A. testa parva, oblongo-fusiformi, alba, nitidiuscula, solida; anfracti- 
bus 5—6, quorum apicalis heterostrophus, levis, vitreus, ceteris 
apud suturas gradatulis, pulcherrime cancellatis et decussatis, 
costis ad juncturas sulcorum spiralium nitidis, gemmulatis ; 
apertura ovata, labro paullulum incrassato; columella fortiter 
uniplicata. 
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. 
Acteopyramis brevicula, sp.n. (Pl. XXII. fig. 4.) 
A. testa minutissima, abbreviata, alba, compressiuscula, solida; an- 
fractibus quatuor, quorum apicalis heterostrophus, vitreus, levis, 
ceteris suturis gradatulis, longitudinaliter crassicostulatis, spira- 
liter undique rudiliratis; apertura ovata, apud basim paullum 
incrassata ; columella uniplicata. 
Long. 1°75, lat. 1 mm. 
Hab. Persian Gulf, Sheikh Shuaib I., 15 fathoms. 
Very minute, but characterized by its compressed abbre- 
viate form and rude sculpture, the whorls all gradately 
angled at the upper part. ‘Vhe figure hardly shows the ribs 
sufficiently prominently, and there is no decussation or granu- 
lation to speak of. 
Pyrgulina manore (Melv.). (Pl. XXII. fig. 5.) 
Turbonilla (Pyrgostelis) manore, Mely. Mem. Manch. Soc. vol. xliii. 
(1898), no. 4, p. 23, pl. 1. 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 Hdgari7, Melv., and 
interstriata, Souv., in spite of the apparent absence of the 
columellar plait. ‘he original specimens came from off 
Manora Point, Karachi, where they were plentitully dredged 
at a slight depth by Mr. Townsend. 
Scala (Constantia) intertevia, sp.n. (Pl. XXII. fig. 6.) 
M, testa gracili, fusiformi, albida, delicata; anfractibus 10, quorum 
apicales tres parvi, vitrei, leves, cylindrici, ceteris ad suturas
