Stat. 273. Pulu Jedan, East coast of Aru-islands. 13 M. Sand and shells. 1 Spec.

The specimens agree rather well with the figures and descriptions of Reeve and Tryon 

 (1. c.) and also with the description of Mörch (Proc. Zool. Soc. Lond. 1860, p. 409), but neither 

 with the figure of Chenu: Illustrations conchyliologiques, Siliquaria, PI. 2, fig. 1, quoted by Mökch 

 nor with the description of that author (1. c. p. 2), who says a. o. : "coquille semitransparante, 

 tres lisse, avec la fissure inarticulée", instead of an articulated slit, closed behind, open near 

 the aperture, like Mörch, Reeve and Tryon have stated. Lamarck's description (1. c.) agrees 

 with that of Chenu, as may be stated by a copy of his diagnose: "S. testa contorta, parvula, 

 semipellucida, candida, laevissima, fissura inarticulata". 



Vermetus Adanson. 



This genus is still more perplexing than the former, as has been discussed by Tryon 

 in his introduction of the genus (Man. of Conch. Vol. VIII, p. 163). I have only been successful 

 in identifying two of the species and even not quite satisfactorely. 



1. Vermetus renisectus (Carpenter) Mörch.

Stat. 100. 6°u'N., I20°37'.5 E. Sulu Sea. 450 M. Dead coral. 3 Spec. (in a cluster). 



Stat. 172. Island Gisser. Reef. 1 Spec. 



Stat. 310. S°30'S., ii9°7'.5 E. Flores Sea. 73 M. Sand with few pieces of dead coral. 1 Spec. 



Stat. 315. East of Sailus Besar, Paternoster-islands. Up to 36 M. Coral and Lithothamnion. 4 Spec. 



The specimens from the first-named Station are bleached, they will probably not have 

 lived at that great depth, that from Stat. 172 is fixed on the hollow side of what seems to be 

 one of the squamae of a large Tridacna. 



var. ? 



Stat. 315. East of Sailus Besar, Paternoster-islands. Up to 36 M. Coral and Lithothamnion. 

 2 Spec. (cluster). 



Appears to be a dark-brown variety of V. renisectus, with somewhat faint lamellae. 



It is however impossible to me, to decide to which of the numerous varieties described by 



Mörch it may belong. 



2. Vermetus sp. 



Stat. 299. Buka- or Cyrus-bay, South coast of Rotti-island. 34 M. Mud, coral and Lithothamnion. 

 2 Spec. 



The specimens are strongly ribbed, probably young. I cannot identify them.
