304 Messrs. J. C. Melvill and R. Standen on 
A pure white, polished, fusiform species, very slightly 
attenuate; upper whorls gradate, all slightly channelled 
suturally, more or less straight. Mouth somewhat square, 
outer lip porrect, squarely produced at the base. Columella 
oblique, simple. Several specimens occurred. Not so elegant 
as HH. katsensis, Melv., the only other of the genus yet 
recorded from this region. “ Carmania,’’ from whence the 
specific name is taken, is the ancient name of that portion 
of Persia impinging on the northern shores of the Gulf 
of Oman. 
Syrnola mussandamica, sp.n. (Pl. XXII. fig. 1.) 
S. testa parva, candida, nitida, polita, semipellucida: anfractibus 
duodecim, quorum duo apicales heterostrophi, bulbosi, cateris 
apud suturas haud profunde canaliculatis, nitidis, politis, ultimo 
longitudine penultimum et antepenultimum anfractum exequante; 
apertura ovata, labro haud effuso, tenui; columella obscure 
uniplicata. 
Long. 5°50, lat. 1°50 mm. (sp. min.); long. 7, lat. 2 mm. (sp. maj.). 
Hab. Gulf of Oman, Mussandam, 47 fathoms. 
A shining, white, polished shell, somewhat excavate at the 
sutures, twelve-whorled, of which the five lowest are much 
the same girth. The apical whorls are heterostrophe, in 
common with all of the Pyramidellide. There is no Syrnola 
very near this in the North-Indian fauna; indeed, it seems 
to impinge closely on Hulimella. 
Mormula persarum, sp.n. (Pl. XXII. fig. 2.) 
M., testa pergracili, attenuato-fusiformi, ochraceo-brunnea, tenui ; 
anfractibus 12, quorum apicalis heterostrophus, levis, albo- 
vitreus, ceteris ventricosulis, apud suturas impressis, arcte longi- 
tudinaliter costatis ; costis obtusis, crassis, 1nterstitiis spiraliter 
liratis, liris supra seepe evanidis, obscure undique infra suturas 
ad medium uni- vel bi-albizonatis, ultimo anfractu infra peri- 
pheriam ad basim planato, simpliciter spiralilirato, anfractibus 
interdum varicosis ; apertura rotundo-ovata, labro tenui, dorsali- 
ter varicoso, albo-stramineo vel brunneo ; columella alba, recta. 
Long. 12°50, lat. (ad aperturam) 3°50 mm. 
Hab. Persian Gulf, Gulf of Oman, Maskat, 15 fathoms. 
Allied to M1. Macandrew, A. Ad., but with more regular 
whorls and ribs, the varices being fewer and less pronounced. 
The colour also is more uniform, being of a warm fuscous 
chestnut, and the outer lip not denticled within. A remarkably 
elegant shell.
