“ Tube assez grand, & coupe circulaire, contournée irréguliérement, 
a stries d’accroissement grossitres, rugueuses, et d’autres fois pourvu 
de deux 4 trois petites cétes ou carénes longitudinales, dentiféres, ou 
mieux tuberculeuses. Couleur d’un rouge brun, mais quelquefois 
blanche. Cette espéce, qui offre une premiére variété, dont les tubes 
sont subsolitaires, et une autre ov ils sont subanguleux et agglomérés, 
vient des mers de l’Asie australe. Elle n’est peut-¢tre pas distincte 
de la 8. arenaria, qui, comme elle, n’est qu’un Vermet. Un individu 
de la collection de M. Lamarck m’a méme offert son opercule corné.”” 
—Blainv. Dict. Se. t. xlviii. 1827, p. 558. 
In Mr. Cuming’s collection are several specimens from Australia 
which seem to me to agree pretty well with the above description, but 
which differ from the uppez figure of Chenu in having less prominent 
nodules. The lid mentioned by Blainville is very likely found in the 
var. 0. of Lamarck, which I suppose is Siphonium nebulosum, Dillw.

The Vermetus dentiferus (Q. & G.) approaches this variety in 
shape, but looks very different in colour and in the form of the 
aperture. The following species is very likely only a narrow form 
of the type, depending on its being agglomerated.

The description and locality of Lamarck seem to me to agree 
perfectly with the shell represented by Chenu, which has also the 
same calibre as the Dofan (Adanson), quoted, with a query, by La- 
marck. ‘This shell differs only from the preceding species in its 
smaller caljbre, very likely dependent on its being agglomerated
