OF CONCHOLOGY. 121 



Mr. Reeve is widely mistaken in referring striata to fulvescens, 

 Rve., as will be seen by his figure of that species. It approaches 

 nearer to decurtata, Rve.

Mr. Adams very properly separated 31. flammea, Rve. non 

 Quoy, under name of M. Philippinarum in P. Z. S. London, 

 1851, p. 141. M. flammea, Quoy, appears however in Conch. 

 Icon. &s flammigera, Rve., of which we hold interlirata, Rve., to 

 be a variety. Of the latter species we have specimens from the 

 East Indies and Philippines, received from Dr. Morch and Mr. 

 Cuming, which are identical as to sculpture with flammea, 

 Quoy, the interliration not being constant on specimens from 

 either locality, and they agree in every respect with Hawaiian 

 specimens. The spire of flammea is produced, rendering the 

 shell more slender and fusiform, as remarked by Mr. Reeve.

The Enc. Meth. should be referred to for description of this 

 species. It varies in color, size and the shape of its transverse 

 ribs. I have found it necessary to retain sixty specimens to 

 illustrate it. The transverse ribs toward the base, are usually 

 angulated, occasionally the angulation extends over those above; 

 they are also plane or sometimes rounded. All the figures and 

 description refer to one variety of color, reddish with a white 

 band or spots. It is frequently, however, wholly of a reddish 

 brown, on which specimens the color of the aperture is darkest. 

 It is covered with a yellowish epidermis, which is striated longi- 

 tudinally. At the Paumotus a variety occurs, wholly white, of 

 which the aperture is also white. A very pretty variety is 

 found at the Ralick Islands, of diminutive size, 10 mill, in 

 length, wholly dark red, the transverse grooves on some speci- 

 mens being traversed by a very minute raised striae. The variety
