of the spire are not twice as broad as high. The basal distinctive 

 groove is nearly square-cut ; its bottom is closely traversed by 

 wrinkles of increase, and is flat, not concave. 



2. Pseudoliva nassoides. Testa parva, solida, imperfo- 

 rata, ovali-conica, fidvo-rufescens 3 laevigata. Ultimi anfractus 

 antice satis declivis fere quartam partem segregat sulcus latus 

 profundus. Cingulum siphonale pallidum retusione cinguli basalis 

 fit prominentior. Spira satis producta tertiam partem longi- 

 tudinis testce implet ; sutura simplex anfractus ejus 4 convexos 

 profunde dividit : apex obtusiusculus. Apertura parva, sub- 

 elliptica, antice posticeque angustata, dimidiam longitudinem 

 testce haud multum superat. Labium columellare crassum, 

 album, Iceve, callo pliciformi nullo postice munitum, sed ad ex- 

 tremitatem anticam subuniplicatum.

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 rather conspicuous. 



3. Dolium fa van nil Testa subglobosa, magis minusve va- 

 lid a, longitudinaliter arete corrugata, fulvo-rufescens, costis 

 {quarum circiter 16 anfractum ultimum, et 4 penultimum cin- 

 gunt) a maculis brunneis pallidisque remote tessellatis, latius- 

 culis, rotundatis, et valde prominentibus, conspicue ornata. 

 Sulcorum inter stitialium (qui costarum magnitudinem cemulan- 

 tur) pauci in anfractu ultimo superiores, omnesque in gyris spirce 

 brevissimce humilibus linea elevata divisi. Sutura excavata. 

 Labium exterius repandum : labii interioris lamella haud (ut 

 in D. fimbriato) libera extans. Exitus umbilici satis magni 

 latus et Icevis. Extremitas cinguli siphonalis rotundati emi- 

 nentis et inconspicue porcati haud caudata.

This very rare shell is intermediate in aspect between D. chinense 

 and D. fimbriatum : from the former it may be distinguished by 

 the pattern of its colouring, and the coarseness and fewness of its 

 ribs ; from the latter by its very dissimilar shape, its umbilicus, &c. 

 The whorls, which rise concavely from the profound suture, do not 

 gradually taper above, but seem, as it were, truncated. The rounded 

 body is about as broad as it is long ; its anterior declination is 

 sudden. The spots with which all the ribs, but not their intervals, 

 are painted, are often cloudy. 



Having as yet seen only two specimens (on one of which the last- 

 formed portion of the ribs was roughened by a few irregular raised 

 spiral lines), I cannot say that the outer lip may not, in perfect and 

 adult individuals, become reflected and dentated.
