In the figure of this species (Marine Shells 8. Afr., pl. vi, fig. 7), the 
second row of nodules upon the body-whorl, mentioned by Mr. Sowerby 
in his description, is not indicated. Although not very conspicuous in 
some specimens they are generally more or less observable. The 
umbilicus is much more open in some examples than in others. 
The largest specimen examined, when perfect, probably measured as 
much as 75mm. in length. 
A comparison of a series of specimens in good condition with the 
type of L. imbricatus, now in the British Museum, shows that they all 
belong to one and the same species. Z. ambricatus was described from 
a somewhat immature specimen in which the labrum was undeveloped. 
126. Larirus PoLyGonus, var. 
Turbinella polygona (Gmelin): Reeve, Conch. Icon., vol. iv, pl. i, 
figs. la-c; Kobelt, Conch. Cab., pl. xvii, figs. 1-7; Kiener, 
Cog. Viy., pl. xiii, fig. 2. 
Hab.—Off Durban, in deep water (Quekett). 
The single example obtained differs from the typical form in having 
the body-whorl more prolonged anteriorly, and in the absence of the 
angulation at the middle of the body-whorl and in the less pronounced 
character of the longitudinal costation. The coloration is practically 
the same. 
127. Latrrus aLsoapicatus, Smith. 
Latirus alboapicata, Smith: Journ. Conch., vol. x (1902), p. 250,

Hab.— Durban. 
128. PrristeRNIA LEUCOTHEA, Melvill. 
Peristernia leucuthea, Melvill: Mem. & Proc. Manchester Lit. & Phil. 
Soc., ser. Iv, vol. iv (1891), p. 399, pl. ui, fig. 15. 
Euthria eburnea, Sowerby: Proc. Malac. Soc., vol. iv, p. 1 (1900), 
plea, fig. 2. 
Hab.—Port Natal (Melvill); Isipingo and Umkomaas (Brit. Mus.) ; 
Pondoland (Sowerby). 
The Euthria eburnea (the type of which is in the British Museum) 
was founded upon very much worn and bleached specimens of this 
species. So worn are the shells that the columellar folds are almost 
obliterated. Mr. Melvill’s figure does not well represent the species, 
which, moreover, is not always white, some specimens being stained 
with orange or rich brown below the suture and between the coste, 
with a colour-band round the middle of the body-whorl and another 
a little below it. The aperture and columella may be purplish or 
purplish brown, and the three columellar plice are distinct in some 
examples, whilst in others only one or two are present.
