MELANIIDA. 235 
Dr. Hungerford sent these specimens mixed with the pre- 
ceding. I think, however, they must be distinguished, as they 
are of a uniform sombre coloration, without any sculpture 
whatever; they are of all stages of growth, but still are in all 
cases decollated and eroded; M. Brot’s pl. 24, fig. 3A. [“M. 
kanaiensis’’},'fig. 7 [“ M. corporosa”’], and fig. 15 [M. lutosa”], 
well represent the form. Long. 37, diam. 15 mil.; anfr. 3. 
25. Melania [Striatella] graeffei,’ 
Melania graeffei [Mousson], Brot, Conch.-Cab. II, 1877, Fiji, and of Cat. 
Mus. Godeffroy ; = M. lutosa, Gild., var., Mousson, J. de C., 1869, 
1 Ovalau; exc. F. Layard, Esq. [labelled “M. costata”’], 
26. Melania [Striatella] newcombi. 
Melania newcombi, Lea, P. Acad. Philad., 1856, Oahu ; = MW. oahuensis, 
Brot [as of Pease]; var. = M. contigua, Pease, Am. J. Con. 1870, 
Kanai,—long. 28, diam. 9 mil. 
6 Sandwich Islands; coll. H. Pease, Esq., and Prof, W. Newcomb. 
27. Melania (Striatella] unifasciata. 
Melania unifasciata, Mousson, Moll. Java, 1849. 
20 Java; coll. Baron F. von Richthofen. 
Very variable, as regards sculpture; some have distinct 
longitudinal sculpture near the apex, which in others is almost 
or altogether obsolete; there are 1 to 3 spiral, incised strie on 
the lower portion of each of the last few whorls, The basal 
band is less distinctly marked than in Mousson’s figure,—indeed, 
generally not visible at all within the aperture. A single 
specimen is of a uniform dark-violet colour; several are slightly 
maculated with brown; these resemble very closely M. tigrina, 
Hutton. 
var. [? dist. sp.]. 
2 Badulla, Ceylon; coll. F. Layard, Esq. 
Anfr. 6; long. 18}, diam. 44 mil. Sent to me as “ Melania 
n. sp. 7?” ; almost smooth, traces of sculpture only being here 
and there discernible; basal band round the columella very 
broad and distinct, otherwise of a purplish-brown uniform 
coloration.
