rather farther apart, and not so deeply snloatcd. ^l. Desliayes, 

 believini;- that Linuicus had before him a fossil from linguon when 

 dctinin<-''his Dentalium ebumeum, and that the latter was wrongly 

 labelled as coming from the Indian seas, regarded the J), ebumeum 

 of Linm^jus as identical with the Parisian shell, but from a careful 

 examination of the recent J), eburneum, Linn., it is evident that 

 M Dcshayes was mistaken, since the Indian shells agree very Aveli 

 with the original Liumvan di^^cription, and differ from the Calcaire 

 Grossier specimens. U. D'Orbigny recognized this fact, and accord- 

 ingly substituted the name I), ebumeum. Very rare; only three 

 mutilated specimens in the Museum.

 There seems to be some doubt as to the type species of Gray^s 

 Entalis. In his description he merely says " JJentaUum e. Desh. _182o. 

 We have therefore followed Stoliczka in regarding I), entalis, Lmn., as 

 the type which is described by Linnaeus—" Testa tereti subarcnata 

 continua Icsvi.'' On consulting the various authors' works cited by 

 the last-mentioned writer, we come to the same conclusion as lorbes 

 and Hanley, namely, that the figures referred to by Lmnoeus are so 

 badly rendered that it is impossible to definitely ascertain the exact 

 limits of this species ; we have, therefore, adopted their views and re- 

 stricted the species to the Swedish form. That form is practically 

 smooth, with a short broad fissure at the postenor extremity. _ 



We are compelled, however, to alter the name Mitalis, since that 

 term had already been used in another sense both by Defrance and 

 G B Sowerby f and we, therefore, propose a new name, Entaliopsis 

 The fossil species here included diiier slightly from the type, inasmuch 

 as tliev exhibit longitudinal strite, which become more or less etiaped 

 on approaching the anterior portion of the test. The fissure is identical 

 with that of D. entalis, and we do not consider the possession of the 

 stria) of generic importance.
