M. SUBULA, Reeve. PL 20, fig. 94. 



Closely reticulated with longitudinal and revolving lines, 

 with a flatly obtuse keel near the suture, lip-sinus distinct; 

 yellowish white, painted with chestnut spots around the guture. 

 Length, 15 mill. 



Philippines, coarse sand, 7 fms. (Cnming) ; 



Darnley I., Australia (Brazier). 



M. FAIRBANKI, Nevill. PI. 22, fig. 48. 



Ribs rounded, distant, continuous, crossed by distant revolving 

 riblets which swell upon the ribs; leaden brown, stained with a 

 darker shade on the outer lip and columella. Length, 6 mill. 



Bombay ; probably also Ceylon, arid Andaman Is. 



Closely allied to M. hexagonalis, Reeve, but differs in the 

 dentate aperture, shorter and more open canal, more distant and 

 distinct revolving sculpture. 



M. DEBILIS, Pease. PL 25, fig. 33. 



Narrowly angulated at the suture, from which descend about 

 ten longitudinal ribs, closely and finely crossed by revolving 

 striae ; white, back of body-whorl stained with chestnut. 



Length, 6 mill. 



Paumotus Is. 



Described as Cythara dsedalea, which name being preoccupied, 

 was subsequently changed as above. 



M. HIRSUTUM, Folin. PL 30, fig. 75. 



Yellowish white, the earlier whorls darker. Length, 3-4 mill. 



Pacific Ocean, on Meleagrina. 



M. BOAKEI, Nevill. PL 33, fig. 71 ; PL 25, fig. 36. 



Whorls narrowly round-shouldered at the top ; longitudinal 

 plicae close, small, rather straight; no revolving striae; pinkish 

 white, shining, with a subsutural interrupted chestnut band, and 

 another about the top of the aperture, lower half of bodj^-whorl 

 pale chestnut ; interior two-banded with chestnut ; lip thickened, 

 internally minutely crenulated. Length, 12 mill. 



Ceylon, So. Australia. 



I think that M. bicinctula, Nevill (fig. 71), will prove to be 

 identical, and M. bella, Ad. and Angas (PL 25, fig. 36), from 

 Rapid Bay, So. Australia, may also be considered a synonym.
