The sprciniciis suft'icioiuly agree with ihi^ rigures of Sowerhy (Thes. Conch.) copied by 

 'Irvon, better than with the other quoted ligures. Ihe oemis, after TROsniKr/s researches on 

 the radula has been commonly classified amongst the 7oxoj^/ossa. Pklsknkkk : Introduction a 

 I'etude des MoUnsques, in: Ann. de la Soc. Roy. Malac. de Belgique, Tome 27, 1892, p. 129, 

 has located the genus as a family between the Volutidae and Miiricidae^ consequently amongst 

 the Rachiglossa. Now in 1903 Dr. Thiklk (Die beschalten Gastrop. der deutschen Tiefsee-Exp. 

 1898 — 1S99, p. 171) has found that the radula has onl\' one row of teeth and no poison-gland, 

 and concluded that the genus should be located near Valuta. I have followed this view, thouirh 

 not without doubt. I found an object agreeing in general appearance with what Thiele (I.e. p. 172) 

 has described as the maxilla, but the point is much longer and the basal wings are less developed 

 than in Thiele's figure (I.e. PI. 9, fig. 69); it seems likewise to consist of two cohering lateral 

 parts and is very finely striated, as is the case in Thiele's figure (1. c. PI. 7, fig. 69a). The 

 shape is shown in my plate, though I must confess, that it is merely a sketch, as the object 

 had suffered by boiling and was broken when I examined it. As to the radula, I have found 

 another complex, agreeing with the description of Troschel as far as concerns the separate 

 elements, called teeth by Troschel (Gebiss der Schnecken, Vol. II, p. 45, PI. 4, fig. ii — 13); 

 their arrangement in the Siboga specimen has however more the appearance of consisting of 

 two lateral rows, at least they lay nearly spread into two bundles, one towards the left the 

 other towards the right side of a central line and at first give more the impression of being 

 the two halves of a widely expanded maxilla than of a radula.

The specimen being very young and small, I could not identify it. Mr. Smith after 

 comparing it with the British Museum-specimens, writes: "I think it must be the young of 

 textilis Kiener".
