The specimens have a more or less juvenile appearance, the largest being only 24 Mill, 

 in length; on account of the shape and sculpture I think they belong to var. borneensis or 

 somewhat intermediate forms, between this variety and typical A. striata.

Shell oval, broader behind, thin, depressed, anterior slope nearly straight, posterior and 

 side slopes convex, the blunt apex placed at about ^/^ of the total length, surface radiately 

 many-striated, the striae are slightly irregular, at intervals stronger, more crowded at some 

 parts of the shell, the interstices have nearly microscopical striae; the radiating striae are crossed 

 by minute, scaly, concentric striae, much weaker and often obsolete in the interstices. Colour 

 very variable, yellowish -white, often with brown rays and adorned with brown lines, which form 

 a more or less complete network, many specimens with conspicuous white spots, especially at 

 some distance from the apex. The dark rays may be wanting or broken up in dark spots. 

 Interior of the shell bluish-white, porcellaneous, the margin more or less dark, according to the 

 external colour-pattern ; central area yellowish-brown. 



Long. 20, lat. 16, alt. 5 Mill, (typical specimen). 



Long. 18, lat. 16, alt. 7Y„ Mill, (from Stat. 86). 



Allied to the preceding species, but differing by the large number of striae, which are 

 squamous and by the pattern of coloration. Perhaps it has hitherto been confounded with striata, 

 with which it lives at the same localities. 



The only specimen from Stat. 86 differs in shape from those from the other localities, 

 being more conical and less elongate, as however it agrees in other respects, especially in colour- 

 pattern, I think these differences may be individual.
