(see E. histrio) the margin having 3 large denticles with only one small one on each side, but 

 not between the larger cusps, moreover the distal cusp of the central ones is not so long; as to 

 the small denticles of the median tooth, this difference may be individual, one finds often such 

 accessory denticles in one specimen but not in another, or even in different rows of the same radula.

1. Metuia daphnelloides Melvill and Standen. 



Melvill & Standen. Arm. and Mag. Nat. Hist. Ser. 7, Vol. XII, 1903, p. 30, PI. 22, fig. 9.

The specimens are dead and the majority is bleached, however one small specimen 

 possesses "the obscure straw maculations". I was struck by the peculiar shape and sculpture 

 of the nuclear whorls, as described 1. c, but was not quite certain about the identification, as 

 the whorls seemed to be more convex and the peristome was much more contracted below. 

 Mr. Melvill had the kindness to compare them with his typical specimens and is of opinion 

 that though the canal of the larger specimens is more produced, it is identical with M. daph- 

 nelloides. Metuia andamanica Smith (Ann. and Mag. Nat. Hist. Ser. 7, Vol. XVII, 1906, 

 p. 165) seems to be the nearest ally, the description of the nuclear whorls being very similar.
