72 rROCEEBINGS OF THE MALACOLOGTCAL SOCIETV. 



Angled at the periphery of the body-whorl, this typical Eidhna 

 much resembles in form Niso venom, Sowb., from the same region, 

 the var. pum of this species occurring sparingly in the same shell- 

 sand. But there is no umbilicar perforation present, and the affinity 

 is merely superficial. Two or three examples have, so far, alone 

 occuri'ed. It is of the same alliance as A\ Shophndi^ Melv., and 

 E. Getitilomiana, Issel, but the peripheral angle gives distinctive 

 characters. 



Edlijia rh.eba,' n.sp. PL VII, Fig. 7. 



E. testa parva, aciculata, ad medium leniter incurva, subpellucida, 

 lacteo-vitrea, perlaevi, delicata, anfractibus ad 10, quorum apicales 

 2-3 nitentes, vitrei, Isevissimi, cfeteris ad suturas parum impressis, 

 arctis, coudensatis, apertura anguste oblonga, labro tenui, simplice, 

 columella obliqua. Long. 3, lat. '75 mm. 



One of the smallest of the genus, but not the least interesting, being 

 allied to the European U. r/iilippii, Weink., also known as distorta, 

 Phil, non Defrance, and mcurra, Renieri. I have closely compared 

 it with this variable species. It occurred but sparingly in shell-sand, 

 and its discovery is due to the energetic sifting of Mr. J. Wilfrid 

 Jackson. 



Mdmiola epibatura,- n.sp. PI. VII, Fig. 5. 



M. testa minuta, angusta, fusifornii, alba, rimata, delicata, anfrac- 

 tibus 6-7, quorum apicales vitrei, leeves, paullum planati, cseteris 

 fortiter gradatis, arete sed indistincte longitudinaliter costulatis, 

 spiraliter arctissime striatis, apertura ovato-rotunda, labro paullum 

 etfuso, columella fere recta. Long. 3, lat. 1 mm. 



A puzzling form, occurring extremely rarely in shell-sand. I am 

 not sure as to its proper location, but in several ways Mumiola seems 

 best suited to it. The peculiarly flattened apex is curious ; the mouth, 

 too, is small, proportionately speaking. 



MccRONALiA RrzoNULA, u.sp. PI. VIII, Fig. 31. 



M. testa minuta, attenuata, fusiformi, laevissima, polita, tenui, 

 subvitrea, anfractibus 8, quorum 4 mamillati, caudati, irregulares, 

 vitrei, ochrotincti, caeteris ad suturas vix impressis, lievibus, spiraliter 

 zona brunnea cingulatis, ultimo bicingulato, peristomate tenui, ad 

 suturam paullulum sinuato et effuso, ad basim producto, columella 

 obliqua. Long. 3, lat. 1 mm. 



A very minute, attenuately fusiform species, the upper whorls 

 spirally once rufous or brown-banded, bizoned on the body-whorl, 

 after the fashion of certain Liofitracce. A very few specimens have, so 

 far, been found. Indeed, the three Ilucroiudid} that occur together in 

 the dredging at 156 fathoms are all of decidedly rare occurrence.
