Long. 7, lat. 2 ram. 



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



We are indebted to Mr. Ernest R. Sykea for calling our attention to this curi- 

 ous little species, so like a Fusus in miniature. It is one of the narrowest 

 ClathurelloB in proportion 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 colouration of some kind. It is 

 common at the above station, in company with another nearly allied Clutlmrella 

 that we hope to describe shortly. 



CLATUURELLA QUISQUILIA*, ep. n. (PI. D. fig. 7.) 



C. testa attenuata, fusiformi, angusta, solidula, omnino albida ; anfractibus 

 9 — 10, quorum duo apicales bulbosi, keves, vitrei, cceteris paucicostatis, costis 

 crassis, numero ultimum apud anfractum 5, spiraliter undique liris rudibus 

 succinctis ; apertura ovato-trigona, labro incrassato, sinu lato sed non pro- 

 f undo ; columella 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 through- 

 out with markedly coarse lirations. It did not occur at all plentifully at the 

 above station, only three or four examples having as yet been seen. 

 DAPIINELLA (PLEUROTOMELLA) NEREIDUM^, sp. n. (PI. D.fig. 2.) 



D. testa ovato-oblonga, subpellucida, delicata, albo-lactea ; anfractibus 8—9, 

 quorum 2^ vel 3 apicales pallide rufi, tcnuissime decussati, cceteris ad medium, 

 angulatis, ad suturas paullum impressis, arete canccllatis, interstitiis quadra- 

 tulis, costis lirisque transversis crystallinis, ultimo anfractu supra medium 

 angulari, costis dorsaliter juxta labrum saope evanidis ; apertura anguste 

 ovata, intus alba, labro tenui. 



Long. 7, lat. 3 mm. 



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



A crystalline form of unusual beauty. In form this assimilates P, filifera 



Dall,but the apical whorls are not smooth, but decussate. 



DAPIINELLA {PLEUROTOMELLA) AMPIIITRITES%, sp. n. 



(PI. D. fig. 3.) 



D. testa ovato-cylindrica, delicata, subhyaliua, albo-lactea ; anfractibus 7 — 8, 

 quorum 2§- apicales albi, sub lente pulchrc decussati, ceteris longitudinaliter 

 lirato-costulatis, spiraliter liris crassioribus succinctis, ad juncturascostularuin 

 cum liris gemmulatis, nitidis, infra medium anfractus antepcnultimi ct penul- 

 timi duabus spiralibus liris magis conspicuis, carinifcris, simul ac in ultimo 

 ad pcripheriam ; apertura ovato-oblonga, intus hyalina, alba, labro tenui, 

 canali brevi, paullum recurvo.
