4 SOLARIUM:. 



glossa, and II. and A. Ad., naming the family Architectonicidae, 



made the same disposition of it. March, likewise, failed to find 

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

 the name A-lossa (Mai. Blatt., p. 129, 1859). 



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

 remarked the affinities existing between the dentition of the 

 Solarmhe and others of the Ptenoglossa (Archiv. fur Naturg., i, 

 p. 91, 18(11). 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, 186<>. 



Reeve, Conchologica.Iconica, xv, Solarium, 1864. 



Kiener, Coquilles Yivantes, Solarium. 



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



A large proportion of the Solariidae were first described by 

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

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

 Plate 14. 



Marquis Monterosato published in 1873 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 Sohiriidiu by Jeffreys, and a few authors have followed 

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

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

 de Conchy liologie, p. 1G6, 1885.
