314 MR. A. ADAMS ON NEW JAPAN SHELLS. [Mar. 14 



The following is a list of the species of Cyclophoridce found by me 

 in Japan, with two exceptions : — 



Cyclotus campanulatus, Martens. 

 Hab. Yokohama {Martens). 



Cyclotus fortunei, Pfr. 

 Hab. Tsu-Sima. 



CCELOPOMA JAPONICUM, A. Ad. 



Hab. Tsu-Sima. 



Cyclophorus herklotsi, Martens. 

 Hab. Tsu-Sima. 



Cyclophorus halophila, Bens., ? = musiva, Gould. 

 Hab. 0-Sima. 



Japonia barbata, Gould. 

 Hab. Tago. 



Japonia citharella, Gould. 

 Hab. Sado. 



Alyc^us japonicus. Martens. 

 Hab. Tsu-Sima. 



Alyc^us spiracellum. Ad. & Rve. 

 Hab. Tsu-Sima. 



PUPINOPSIS ilUFA, Pfr. 



Hab. Japan {Cuming). 



PupiNOPSis MiNDORENSis, Ad. & Rve. =japonica, Mart. 

 Hab. Tsu-Sima. 



DiPLOMMATINA EXIGUA, A. Ad. 



Hab. Tsu-Sima. 



Terebratula davidsoni, a. Ad. (PI. XIX. fig. 30.) 



T. testa ovato-globosa, Icevi, albida, laminis increment i distinctis, 

 irregularibus, ad basin validioribus ; margine ventrali circu- 

 lari ; rostro producto, recurvato ; foramine parvo, perfecto ; 

 deltidio parvo, concavo ; apophysi simplici, ^ longitudinis testae 

 superante. 

 Long. 18, lat. 14, alt. 11 mill. 

 Hab. Satanomosaki, Japan : 55 fathoms. 



This is the fourth recent species of Terebratula (as restricted) 

 known. It most resembles T. uva, from the Gulf of Tehuan tepee, 

 but differs from it in its more solid structure and more globose form, 

 and in the foramen being smaller and entire.
