LIpARUS SPENCERI, sp. nov. 
Similar to the short and broad variety of L. melo, but the test 
is thin, diaphanous, and dark horn-colored ; the whorls are more 
convex and abruptly arched at the suture, the aperture slightly 
oblique and proportionately wider (as in L. Onslowi). 
Length, 20; width, 12:5; aperture, 11°5 x 8 mm. 
PLANISPIRA HEMICLAUSA, Sp. nov. 
Shell depressed, glossy; spire slightly prominent ; whorls three 
and a-half, somewhat gradated, distantly and regularly sculptured 
with spiral incised lines, finely transversely striate ; aperture not 
deflected, peristome much thickened, continuous all round, the 
parietal incrassation obliquely in advance and forming a vertical 
plate half-closing the aperture; umbilicus about one-third the 
width of the shell. 
Diameter, 1°5 ; height, about ‘5 mm. 
CHAROPA HMULA, sp. nov. 
Similar to C. antialba, Beddome, with the same number of 
riblets, but apparently inornate in the interstices ; spire slightly 
sunken; umbilicus very much smaller, with regularly sloping 
walls. 
Diameter, 2; height, °75 (vix). 
CHAROPA RETINODES, sp. nov. 
Like C. Morti, Cox, but the riblets more frequent, though 
wide apart, the interspaces regularly reticulate-striate ; last whorl 
feebly flame-painted, and more depressed ; umbilicus larger ; the 
young shells not at all angulate. 
Hapra WArTTII, sp. nov. 
Its only ally is 7. lewcocheila, from the unicolorous variety of 
which it differs, particularly, by more numerous very narrow 
whorls (six and a-half), smaller size, and very small umbilicus, not 
at all concealed by the columella. 
Diameters, 10°5 and 9:25; height, 5-5. 
HADRA SUBLEVATA, sp. nov. 
Has the general appearance of H. Hyrez, but with five narrower 
whorls of less rapid increase, and scabrous-granulate surface ; 
lips callously united, outer lip largely reflected, deeply constricted 
basally, producing a conspicuous elevated ridge within the aper- 
ture (thus resembling H. Wesselensis) ; umbilicus large, 2-5 mm. 
wide. 
Diameters, 15 and 14; height, 8.
