specimens of Achatinella viridans in the valley east of Keawaawa. 

 These shells once thrived there, but the trees that they lived on 

 have died away and consequently the shells have died off with 

 them. 



We all met at the foot of one of the small ridges at about 

 4 o'clock, ready for our homeward journey. Messrs. Emerson 

 and Bryan had returned from their hunting trip. They were 

 successful in wounding a goat and collecting a few specimens of 

 Achatinella viridans on the windward side of the backbone ridge. 

 Mr. Grinnell collected some interesting insects and native plants. 

 After two long hours' walking at a good gait, we reached the car 

 line, and about 6 p. m. we boarded the car for home. 



Thus the Gulick Natural History Club finished its first trip 

 with quite a success in the collecting line. 



The shells listed were identified by Dr. C. Montague Cooke, 

 Jr. 



A NEW VARIETY OF OLIVA SERICEA MINIACEA. 



BY H. C. HIGGINS. 



Having become greatly interested in the Olividae, their 

 beauty and the great variation of the species are to me a never- 

 ending source of pleasure, marred only by the many perplexi- 

 ties in nomenclature. To what extent names should be given 

 to the various forms, authors differ in opinion, but it seems 

 more convenient to refer to certain well-marked forms by name 

 when they are well figured in standard publications, than to say 

 a variation of 0. sericea subspecies miniacea figured in the Thes. 

 Conch., Vol. IV, pi. 7, f. 110. 



Having brought together a remarkable series of 250 specimens 

 of Oliva sericea (tremulina-miniacea group) showing all the named 

 varieties as well as many intermediate specimens, I was im- 

 pressed with the fact that a shell in the miniacea group corre- 

 sponding to variety pica in the tremulina group, has no varietal 

 name, therefore I propose the name Oliva sericea miniacea var. 

 johnsoni for this shell, in honor of Mr. C. W. Johnson, curator 

 of the Boston Society of Natural History, as a slight acknowl-
