costatis, spiraliter striatis ; sutura distincta ; apertura subovali, labio externo 

 incrassato, intus sulcato, interno in larainam prominentem intus antice denti- 

 culatam producto; canali brevissima, recurva, extus striata. Long. 0*4, lat. 

 0-25 poll. 



Nearest to Nassa semistriata, but very different in its form and 

 proportions. 



Nassa proxima. 

 Fig. 31. 



Nassa testa ovato-acuminata, crassa, anfractibus 7 postice biseriatim graniferis, 

 irregulariter costellatis, antice spiraliter sulcatis ; apertura intus costellata, 

 canali brevissima, recurva, extus carinam efformante. Long. I'O, lat. 0-5 poll. 



Nearest to Buccinum baccatum of Basterot ; like that species it has 

 two spiral rows of grains at the posterior part of the volutions, one of 

 which is smaller than the other and close to the suture. It differs 

 from that species in its form and proportions, as well as in having 

 its canal very short and recurved. 



Nassa parvula. 

 Fig. 34 a. mag. nat. — h, c. auctse. 



Nassa testa conico-pyramidali, crassiuscula, longitudinaliter sulcata, transversim- 

 que striata, striis anterioribus fortioribus ; anfractibus senis, subventricosis, 

 sutura valida ; apertura ovali, labio externo extus varice instructo ; interno sub- 

 incrassato, paululiim expanso. Long. 0*4, lat. 0*2 poll. 



This somewhat resembles Nassa macula, but may be distinguished 

 by the form of the volutions, which are much less ventricose ; the 

 transverse strise also are much less prominent. 



Nassa inconspicua. 

 Fig. 35 a. mag. nat. — b, c. auctee. 



Nassa testa conico-pyramidali, crassiuscula, laevigata, antice transversim striata ; 

 anfractibus quinque subventricosis, posticis longitudinaliter sulcatis, transver- 

 simque obsolete striatis, ultimo multo majori, Isevi ; apertura subovali, labio 

 externo varice baud prominente extus instructo, intus denticulato, interno sub- 

 incrassato, paululum, postice praecipue, expanso. Long. 0*4, lat. 0-2 poll. 



By attention to the above characters, this species may easily be 

 known from N. Piisio and N. parvula. This will not be confounded 

 with N. macula. 



VOLUTA SPOLIATA. 



Fig. 32. 



Vol. testa ovato-coniformi, longitudinaliter costellata, spiraliter striata, granulifera, 

 spira brevi, anfractibus quatuor, ultimo raaximo, nonnunquam seriem tubercu- 

 lorum coronato ; apertura latiuscula, postice reflexa, labio externo incrassato, 

 reflexo, intus sulcato ; plicis columellaribus quatuor. 



As there are only casts of this shell, it is obviously impossible to 

 give a full description of the species. The characters given above 

 have been collected from several specimens i one of the most remark- 

 able is the granulated outer surface, in which it resembles no other 

 Volute that we are acquainted with ; this granulated surface is similar 

 to that of Murex lingua-bovis of Basterot.
