*' Descriptions of new species of Scalaria and Murex, from the 

 collection of Sir Edward Belcher, C.B.," by Mr. Hinds. 



ScaLaria glAbrata. Seal, testd elongatd, politd ; anfractibus de- 

 cerns, rotundatiSffere disjunctis; costis membranaceis, vicinis supra 

 et infrd, connatis, prope suturam dilatatis ; anfractu ultimo decem- 

 costato ; aperturd oi^ali; umbilico peritremate tecto. Axis 8 lin. 

 Hab. Amboina ; Straits of Macassar ; Straits of Malacca. On a 

 muddy floor, in from ten to seventeen fathoms. 



The specimens were all obtained without the animal, but the mot- 

 tled appearance which they present seems to indicate, that when re- 

 cent they were most probably of a light brown colour. 



Scalaria Dian^e. Seal, testd ovatd, acuminatd, politd; anfracti- 

 bus septenis connatis, costis valde aleeformibus ornatis ; anfractu 

 ultimo hexacostato, ad basin obtuse carinato ; aperturd rotundatd, 

 inferne subtruncatd ; peritremate eoctils alato ; umbilico nullo. 

 Axis 5 lin. 

 Hab. Gulf of Nicoya ; from thirty-six fathoms, among mud. 

 Scalaria vestalis. Seal, testd ovato-elongatd, pallidd; anfractibus 

 nonis rotundatis, connatis; costis numerosis, tenuibus, sparsim 

 varieosis, lineis transversis eleganter caneellatis ; aperturd ovali ; 

 umbilieatd. Axis 4| lin. 

 Hab. New Guinea; from seven fathoms, among mud. 

 An elegant cancellated species, with numerous fine ribs, which, 

 when becoming varicose, are slightly spined above. The number of 

 ribs on the last whorl appears little liable to fluctuation, and they 

 become a very useful and valuable character in the discrimination of 

 the species. In S. vestalis their number is twenty-two. 



Scalaria suturalis. Seal, testd elongatd, pallide fused ; anfrac- 

 tibus decerns, connatis; costis numerosis, parvis, approximatis, 

 lineis transversis deeussatis, subdistanter varieosis ; suturd et an- 

 fractu ultimo ad basin carinato ; aperturd subrotundd ; umbilico 

 nullo. Axis 8 lin. 

 Hab. Straits of Malacca ; from seventeen fathoms, among mud. 

 An elongated shell; also somewhat cancellated by lines traversing 

 the numerous small ribs. At intervals of something less than the 

 volution of each whorl a thick rounded varix is formed : a keeled line 

 also occupies the most inferior portion of the whorl, close to the su- 

 ture. The specimens had been left by the animal some time previous 

 to being captured, and though they are not in very good condition, 

 there still remains a disposition to a dark brown banding. 



Scalaria aciculina. Seal, testd elongatd, politd; anfractibus 

 decerns subdisjunctis ; costis rotundatis, superne angulatis ;
