The species of Avellana sent to Mr. Suter is described in this volume 

 (p. 120) under the name Avellana paucistriata Marshall. In addition to the 

 species in this list, Turritella seyniconcava Suter is abundant, and I also 

 found Pugnellus australis Marshall and Avellana curta Marshall. The last 

 two of these are described elsewhere in this volume (pp. 120, 121). Suter 

 has stated on Park's authority that Conchothyra, Aporrhais, and Beleninites 

 occur as well, but I could find none of them, though the occurrence of 

 Belemnites in strata of the same age at Brighton makes it quite possible 

 that this genus at least is represented. 



The molluscan species in this collection thus total fifty-two, and of 

 these the three species Pugnellus australis Marshall, Avellana paucistriata 

 Marshall, and A. curta Mai-shall belong to genera which are not known to have 

 representatives in strata higher than the Cretaceous. Of these two genera 

 Pugnellus is usually Senonian, but Cossmann mentions no species of Avellana 

 in strata higher than the Cenomanian. There are twenty-six other ex- 

 tinct species, and of these one- — Roxania n. sp. — belongs to a genus not
