34 THE NAUTILUS. 



A miniature Polintces, resembling P. montayui Forbes and P. 

 pallida B. & S., but very distinct by its conspicuously excavated 

 suture (bathyraphe, deep suture.) 



SCALA STIGMATICA n. Sp. 



Allied to S. maculosa Adams & Reeve. The shell is barelj 

 rimate, white, marked below the perifery with oblique oval brown 

 spots in each inter-lamellar space, and sometimes with a few faint 

 ones above the perifery. These spots are not sharply defined, but 

 fade at their edges. The spire is straightly conic; embryonic whorl 

 or whorls wanting in the specimens seen. Succeeding whorls are 

 well rounded, separated by deep sutures. The last one or one and 

 a half whorls are so deeply separated that they seem to be in 

 contact only at the ribs. There is a very minute sculpture of fine, 

 close, unequal engraved spiral lines in the intercostal spaces. The 

 ribs are rather low and narrow, without points at the shoulder, or 

 with them very indistinct ; at irregular intervals there are larger, 

 heavier ribs. Each of the last two whorls has eight ribs. The 

 aperture is oblique, short-oval ; peristome continuous, with a strong 

 lip-varix. 



Length 24, diam. 8^ mm.; whorls remaining 9^. 



Length 20^, diam. 8^ mm.; whorls remaining 10.

This species was determined as new in 1904, and was sent out 

 under the above name by Mr. Hirase. Subsequently I thought it 

 might be a form of S. maculosa A. and R., and the description was 

 therefore withheld. Mr. G. B. Sowerby, who received specimens 

 from Mr. Hirase, has kindly informed me that it is quite distinct. 

 S. stigmatica is " much larger than maculosa, whorls more 

 rounded, ribs more distant, and not at all angular or acnleated " at 

 the shoulder.
