new Gastropoda from the Persian Gulf, &e. 315 
miniature, It is one of the narrowest Clathurelle in pro- 
portion to its length yet discovered, and is wonderfully 
symmetrical throughout. All the examples, of which there 
are several, are dead, and perhaps in life there may be 
coloration of some kind. It is common at the above station, 
in company with another nearly allied Clathurella that we 
hope to describe shortly. 
Clathurella quisquita*, sp.n. (Pl. XXIII. fig. 7.) 
C. testa attenuata, fusiformi, angusta, solidula, omnino albida; 
anfractibus 9-10, quorum duo apicales bulbosi, leves, vitrei, 
ceteris paucicostatis, costis crassis, numero ultimum apud an- 
fractum 5, spiraliter undique liris rudibus succinctis ; apertura 
ovato-trigona, labro incrassato, sinu lato sed non profundo ; colu- 
mella fere recta, canali brevi. 
Long. 7, lat. 2 mm. 
Hab. Persian Gulf, Mussandam, 47 fathoms; also Gulf of 
Oman, lat. 24° 58’ N., long. 56° 54’ E., 156 fathoms. 
Attenuate and narrow, thickly longitudinally ribbed, and 
encircled throughout with markedly coarse lirations. It did 
not occur at all “plentifully at the above station, only three or 
four examples liaving as yet been seen. 
Daphnella (Pleurotomella) nereidum T, sp. n. 
(Hele POS BMIE res 23) 
D, testa ovato-oblonga, subpellucida, delicata, albo-lactea ; anfracti- 
bus 8-9, quorum 23 vel 3 apicales pallide rufi, tenuissime 
decussati, ceteris ad medium angulatis, ad suturas paullum 
impressis, arcte cancellatis, interstitiis quadratulis, costis lirisque 
transversis crystallinis, ultimo anfractu supra medium angulari, 
costis dorsaliter Juxta labrum sepe evanidis; apertura anguste 
ovata, intus Wie labro tenui. 
Long. 7, lat. 3 
Hab. Gulf of ane lat. 24° 58’ N., long. 56° 54’ E., 
156 fathoms. 
A crystalline form of unusual beauty. In form this as- 
similates P. filifera, Dall, but the apical whorls are not smooth, 
but decussate. 
* Quisquilia, trifles. 
tT Nereidum, of the sea-nymphs.
