LITTORINA. 245 



L. FLAMMEA, Phil. PL 43, figs. 34-36. 



Narrow, thin, whorls slightly convex, the last with obscurely or 

 distinctly angulated periphery, closely spirally striate ; yellowish, 

 tessellated or with zigzag markings of chestnut. Length, 20 mill. 



China. 



Thinner and narrower, and without the violet columella of the 

 preceding species. In the form figured by Reeve as L. Fortunei 

 (fig. 35), the peripheral angle is less prominent. L. luteola, Quoy. 

 (fig. 36), also appears to be a synonym. 



Our museum possesses specimens from Port Natal, South Africa, 

 probably referable to this species. 

 L. ABERRANS, Phil. PI. 43, fig. 32. 



Thin, slender, with rounded whorls and deep suture, finely spi- 

 rally striated, plicately decussated by growth lines ; flesh white, the 

 ridges opaque, lip and columella thinly reflected, tinged with violet ; 

 subperforate. Length, 18 mill. 



Panama 



Described from a single specimen in the Cumingian collection. 

 The locality has not been verified-. Looks as much like a Bulimus 

 as a Littorina, 

 L. STRIGATA, Lischke. PI. 43, fig. 33. 



Inflated, somewhat solid, spirally striate ; yellowish, with inter- 

 rupted chestnut spiral lines, forming oblique strigations. 



Length, 9'5 mill. 



Japan. 



Distinguished by its short, bulbous form. 



L. MELANOSTOMA, Gray. PI. 43, figs. 42, 43. 



Rather thin, whorls flattened, obliquely, obscurely subrugose, 

 spirally distantly engraved, periphery angulated ; straw color, with 

 usually a longitudinal pattern of short, numerous, chestnut lines ex- 

 tending from sulcus to sulcus, either all over the surface or dis- 

 continued at the periphery ; columella dark chocolate.

45, figs. 14, 15.
