NATICA. 15 



Yar. MACULATA, Desh. PI. 2, fig. 24. 



The spots larger, less sharply defined, often interruptedly con- 

 fluent, with three interrupted bands of larger spots or macula- 

 tions. 



Appears to connect closely with the type form, but has been 

 separated as a distinct species of late years by several concholo- 

 gists on account of differences in the lingual dentition. I retain 

 the name by which the species is well known instead of the prior 

 one of N. hebraea, Martyn which has scarcely obtained currency. 

 Other synonyms are N. trifasciata (Recluz), Adams ; N. aspersa, 

 Menke ; N. cruentata, Payr. 



Monterosato has named as color-varieties, fusca, immaculata, 

 and rarimaculata. The latter appears to me to connect with the 

 next species. 



Var. SANGUINOLENTA, Brusina. PI. 2, fig. 25. 



The punctations coalescing into undulating longitudinal flam- 

 mules. 



X. FULMINEA, Gmelin. PL 2, figs 26, 27. 



Shell solid, somewhat tumid and plicately striated next the 

 suture ; umbilicated, but the umbilicus partly covered by an 

 overgrowing callous deposit on the upper part of the columellar 

 lip, which finally becomes A^ery thick ; whitish, with longitudinal 

 undulating or zigzag chestnut markings, sometimes partly broken 

 up into spots ; often peppered with minute spots between the 

 larger markings ; occasionally the zigzag lines break up into 

 three revolving series. Length, 1-1'75 inches. 



West Coast of Africa. 



The synonymy includes N. cruentata and N. arachnoidea, 

 Gmel.; ? N. pardalis, Phil.; N. Ufasciata (Recluz), Reeve; N. 

 punctata, Swainson ; N. Senegalensis, Recluz (fig. 28) has been 

 placed here by Reeve and Sowerby ; the figure has the markings 

 of fulminea, but appears to possess a more conical spire; it is 

 probably distinct. 



N. ADANSONI, Phil. PL 2, fig. 30. 



Small, solid, yellowish maculated and spotted with chestnut, 

 upper and lower portions of body-whorl free from spots, or
