divide into two subfamilies, Melampea and Auriculea, a method 

 very similar to that adopted by the same author in the Mono- 

 graphia Auriadaceorum. 



Keeve (1842) applies the same name to a family of Gastero- 

 poda, comprising the genera Auricula (in which he includes 

 Pedipes), Scarabus, Chilina. A. Catlow (1845) follows him. 



Sismonda (1842) gives the name of Auriculata to a section of 

 Gasteropoda, of which only the genus Auricula is mentioned. 

 _ De Kay (1843) changes the name of the family into Auriat- 

 liadce. 



Kiister (1844) gives an illustrated monograph of Auriculacea, 

 containing the genera Carychium, Scarabus, Auricula (sections 

 Cassidula, Conovtdus, Auricula, Pythia, Tornatellina, Comdus) 

 and Jaminia. 



Hinds (1844) uses Menke's name of Auricidacece. 



Agassiz (1847) proposes to change the name of the family 

 into Auriculina. 



Troschel (1848) places the family of Auriculacea in the second 

 series of hermaphrodite Gasteropoda. 



The same name is used by Jay (1850), and by A. Adams and 

 Eeeve, also by Poey (1854), who enumerates the Cuban genera : 

 Melampus, Pedipes, Odostomia. 



Strobel (1850) changes the name of the family into Auri- 

 culceHna. 



Clark (1850), Ann. and May. K H. vi. 444, regards under the 

 name of Conovulidce a family of Pectinibranchiata, in which he ad- 

 mits the genera Conovulus, Carychium, Acme, and ? Otina, Gray. 

 In his svnopsis of the families and genera of the British testaceous 

 Acephala palliobranchiata and lamellibranchiata, Gasteropoda and 

 Cephalopoda (1851), I. c. vii. 472, the family is only formed of 

 the genera Conovulus, Pedipes and Otina, and Acme and Cary- 

 chium are removed to the Pyramidellidce ; and in his ' British 

 Marine Testaceous Mollusca,' 1855, he places Otina between 

 Bullidce and Conovulidce. 



Stimpson (1851) applies the name of Melampidce to a family, 

 of which the American genera Melampus and Carychium are 

 enumerated. 



Philippi (1853) regards Auriculacea as the fourth family 

 of Pulmonata, including the following genera: Scarabus, Auricula 

 (with the sections Auricula, Cassidida, Carychium, Melamptis, 

 Pythia, Ophicardelus), Pedipes. 



H. and A. Adams have published a recent 'Monograph of 

 Elhbiida] a family of Pulmoniferous Mollusks. 



Among the various genera ascribed to the family of Auricu- 

 lidce by several authors, the following must be excluded from
