apt to be a larger series of granules, with a very small one succeed- 
ing it.

Hab. 2 
Length 1-, diam. *4 of an inch. 
Remarks.—On the last whorl of the only specimen submitted, the 
costee are almost obsolete. The strice are strongest near the sutures, 
and scarcely visible at the middle of the whorls. 
MELANIA LATERITIA. WM. testd cancellatd, acut? ovatd, compressa, 
crassiusculd, striatd, graniferd, albidd, virido-fuscd, rufo fasciatd 
aut atrd; spird elevatd, plerumque scalariformi, apice acutd aut 
erosd; suturd impressd, crenatd; anfractibus decem, planatis, 
superne angulatis, supra angulum sepe albidis ; striis transversis 
crebris graniferis ; granulis quadratis, abruptis, planatis, serie- 
bus longitudinalibus positis; anfractu ultimo magno, subcom- 
presso ; basi graniferd ; aperturd ovatd, superné acute angulatd 
et sinuatd, inferne latd, expansd et retusd, interne sepe fasciatd ; 
columelld contortd ; operculo parvo, ovato. 
Hab. Philippines. 
Length 1-6, diam. *7 of an inch. 
Var. a. Anfractibus superné graniferis, inferne striis transversis 
impressis ; basi vix levi, striis raris. 
Var. 6. Striis graniferis alternantibus. 
Remarks.—A very variable species as to size, colour and sculp- 
ture. The operculum differs much in some individuals in both its 
shape and apex. This shell bears some resemblance to the M. gra- 
nifera, Lam. Its most remarkable characteristic is its square, flat- 
tened granules, bearing some resemblance to brickwork. 
MELANIA MODICELLA. WM. testd levi, ovato-conicd, crassd, nitidd, 
virido-fuscd ; spird conicd, brevi, apice acutd, sepe erosd ; suturd 
lineari ; anfractibus quinque, convexis, rapide crescentibus, prope 
suluram superiorem depressis, prope suturam inferiorem striis 
parvis transversis duabus aut tribus; anfractu ultimo magno, 
medio striis tribus, basi levi; aperturd ovato-rotundd, superne 
subangulatd, inferne subeffusd, intus albidd ; labro acuto; colu- 
mella lacted, curvatd ; operculo ovato, subcentrali, concentrico. 
Hab. Timor. 
Length *7, diam. °5 of an inch. 
Remarks.—This shell and the M. zeylanica may perhaps be taken 
as the types of a new genus or subgenus. Further investigation with 
respect to the animal may decide; in the meantime, the name of
