GLABELLA. 27 



M. AUSTRALIS, Hinds. PL 7, figs. 33, 34 ; PI. 8, fig. 36. 



White to orange-brown ; lip and interior of aperture orange 

 or yellowish. Length, 6-7 '5 mill. 



N. W. Australia ; New South Wales. 



M. Metcalfei, Angas (fig. 34), and M. ochracea, Angas (fig. 

 36), are juveniles of this species. Redfield and Weinkauff have 

 placed as a synonym here M. oryza (= debilis), Pease ; but that 

 species has a crenulated lip. 



M. VITREA, Hinds. PI. 8, fig. 37. 



Milk-white; much more angular and conical than M. mar- 



garita, Kiener. Length, 6 mill. 



W. Coaxt of Africa. 

 M. INCONSPICUA, Sowb. PI. 8, fig. 38. 



Milk-white. Length, 6 mill. 



West Indies (Coll. Philad. Acad.). 



M. SAULLE, Sowb. PL 8, fig 39. 



Pallid fulvous, with two red revolving lines. Length, 7*5 mill. 



Cape Verd Is. (Weinkauff). 

 M. EVANIDA, Sowb. PL 8, fig. 40. 

 Milk-white. Length, 6 mill. 



Lower Guinea Benguela (Weinkauff). 



Dr. Weinkauff suspects that this will prove identical with M. 

 Saulife. 



M. SUAVIS, Souverbie. PL 8, fig. 41. 



Opaline white, with three red-brown bands, the middle one 



broad, the others narrow. Length, 3 mill. 



New Caledonia. 

 M. NEGLECT A, Sowb. PL 8, figs. 42, 43. 



Reddish yellow, three-banded, with red spots. 



Length, mill. 



Cape of Good Hope; Isle of Bourbon (Deshayes). 



The above is the description of M. nifula, Gaskoin. M. 

 neglecta, Sowb. (fig. 42), which is described as pallid fulvous, 

 faintlv, trifasciate, length 6 mill., appears to me to be the 

 same species, and has priority. Jonsseaume supposed Reeve's 

 figure of M. neglecta to differ specifically from Sowerby's shell, 

 and calls the former M. igtwta. I am not nble to separate 

 them.
