Hab. Amboina; Straits of Macassar; Straits of Malacca. Ona 
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. 
Scataria Diana. Scal. testd ovatd, acuminatd, politd ; anfracti- 
bus septenis connatis, costis valde aleformibus ornatis ; anfractu 
ultimo hexacostato, ad basin obtuse carinato ; aperturd rotundatd, 
inferne subtruncatd ; peritremate extis alato; umbilico nullo. 
Axis 5 lin. 
Hab. Gulf of Nicoya; from thirty-six fathoms, among mud. 
Scauania vestatis. Scal. testd ovato-elongatd, pallidd ; anfractibus 
nonis rotundatis, connatis; costis numerosis, tenuibus, sparsim 
varicosis, lineis transversis eleganter cancellatis ; aperturd ovali ; 
umbilicatd. Axis 44 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. Scal. testd elongatd, pallide fuscd ; anfrac- 
tibus decenis, connatis; costis numerosis, parvis, approximatis, 
lineis transversis decussatis, subdistanter varicosis ; suturd et an- 
Sfractu 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. 
Scanarra acicutina. Scal. testd elongatd, politd; anfractibus 
decenis subdisjunctis ; costis rotundatis, superne angulatis ; 
anfractu ultimo decemcostato; aperturd ovali; umbilico parvo. 
Axis 34 lin. 
Hab. West coast of intertropical America. 
ScaLaRIA CREBERRIMA. Scal. testd ovato-elongatd, albidd ; an. 
Sractibus septenis, connatis, costis tenuibus creberrime instructis ; 
aperturd ovali; umbilico nullo. Axis 8 lin. 
Hab. North coast of New Guinea; from seven fathoms, among 
mud. 
The whorls are closely set with ribs, in numbers almost too great 
to be enumerated.
