The specimen belongs to the form with rounded shoulder. 



The radula has the teeth in more than 50 rows; the median tootii (M) is elegantly 

 curved, with 18 to 20 rather long- cusps, becoming smaller towards the sides. The laterals (i) 

 are long, nearly reaching each other towards the centre of radula in their natural position ; they 

 have the common hooked shape.

Stat. 231. Amboina. Reef, i Spec. 



The only specimen which is not quite developed, has but one narrow white line though 

 Adams describes two of them. The whorls are less angular than on the quoted figure of Sowerby, 

 which is also one-banded and in that of Tryon, which is a rude copy of Sowerby's figure. 

 Mr. E. A. Smith compared the specimen with the type.

If wet, the specimens are elegantly lined with fine, brown lines, if dry these are much 

 less apparent, but otherwise I can detect no differences of any importance with the figures.

Stat. 174. Waru-bay, North coast of Ceram. Reef, i Spec. 



Tryon has located this species in the genus Mitra, but though I am not quite certain 

 that I can detect traces of internal lirae, the shape of the aperture and the columellar plaits 

 agree with those of Tztrricula.
