4 SOLARTID^. 



glossfi, and H. and A. Ad., naming the family Arcliitectonicidae, 

 made the same disposition of it. Moreh, likewise, failed to lind 

 teeth, and formed for the family a new group to which he gave 

 the name Aglossa (Mai. Blatt., p. 129, 1859). 



Dr. Troschel found both teeth and jaws to be present, and 

 remarked the athnities existing between the dentition of the 

 Solariidte and others of the Ptenoglossa (Archiv. fiir Naturg., i, 

 p. 91, ISni). This arrangement has been generally accepted, 

 most authors placing Solarium near to Scalaria and lanthina. 



The Solariidse have been monographed by : — 



Hanley (Solarium, Torinia), in Sowerby's Thesaurus Conch}'- 

 liorum,iii, p. 227, 1866. 



Reeve, Conchologica Iconica, xv. Solarium, 1864. 



Kiener, Coqnilles Yivantes, Solarium. 



Philippi, in Kiister, Conch. Cab., 1853. 



A large proportion of the Solariidse were tirst described bj^ 

 Hinds in the Proceedings of the Zoological Society, 1844, and 

 afterwards figured in the Zoology of the Voyage of tlie Sulphur, 

 Plate 14. 



Marquis Montcrosato published in 18t3 a pamphlet entitled 

 " Notizie Intorno ai Solarii del Mediterraneo," having sixteen 

 pages and one plate. 



The genus Adeorbis, Searles-Wood, has been placed in the 

 family Solariidae by Jeffreys, and a few authors have followed 

 this classification. I have deemed it best to exclude the genus : 

 for a discussion of the proper position of Adeorbis, see Journal 

 de Conchyliologie, p. 166, 1885.
