melvii.l: TxENERA pseudoi-iva and MACRON''. 323" 



ornnmented by a deep chestnut-brown margin to the columella, and 

 a tint of the s.ime colour in the mouth. ^ 



M. Paul Fischer in 1884 separated this species subgenerically unier 

 the name oi Fulmcntum sepifnenliun, his diagnosis being — 



"Spire aigue; callosite columellaire large; une forte lamelle interne, 

 placee sur la columelle, cloisonne I'ouverture en arriere; opercule 

 ovale, acumine; nucleus apical. Hal>., He du Prince."' 



A very rare shell; I have only seen the examjile in the British 

 Museum (Nat. Hist.). It appears to me more di\\\e.d to Fseudoliva 

 than Macron, in spite of the operculum being acuminate, with apical 

 nucleus.

 A rare form of which I have only seen the specimen in our 



National Collection. It is about 075 inch in length, smooth, broad,' 



with chestnut lines disposed longitudinally. Owing, no doubt^ to ■ 



the coloratijn, an affinity to Zetnira australis Sowb., has been 



suggested. ^

Pseudoliva 7iassoides Hanley, Proc. Zool. Soc, 1859, p. 430. 



Testa parva, solida, imper/orata, oval is, conica,fu!vo-rufescens, Icevigata, 

 ultinii anfractus antice satis declivis fere quariani partem segregai 

 sulcus latiis profundus. Cingulum siphonale pallidum retusione 

 cinguli basalis fit prominentior, spira satis producta tertiam partem 

 longitudinis testae implet ; sutura simplex anfractus ejus 4 convexos 

 profunde dividit; apex obtusiusculus. Apertu?-a parva, subelliptica, 

 antice posticeque angustata, dimidiam longitudinem teste haud 

 multuni superat. Labium columellare crassum, album, Iceve, callo 

 pliciformi Jiullo postice munitum, sed ad extj-eniitatem anticam sub- 

 uniplicatum. Long. |, lat. -^'^r poll. 

 Hab., Malabaricum littus (Mus. Hanley). 

 The only specimen known to me bears the aspect of being fully 



adult. Its outer lip seems thickened externally, and the tooth-like 



projection over the characteristic groove is conspicuous (S.H.).
