32 THK NAUTILUS. 



sending contains four ?pecinieii!<. Mr. Wick ham sent me two from 

 Victoria: one being immature, only 21 millim. long; in this small 

 specimen the sole was not visibly divided into tracts. There is also 

 a specimen of /". maculatus in the British ^luseiim from Vancouver 

 I. {Lord I. Russell ; coll. by the Boundary Commission), which is 63 

 mill, long (ill alchohol), tail well keeled for 18 millim. ; a large spot 

 on mantle ; sole with median area smooth though wrinkled, lateral 

 area rough ; jaw dark, with 15 ribs. 



(4c) Ariolimax columbianus forma nov. niger. Entirely black, 

 except the sole, vrhich is rather olivaceous. One specimen, 

 57 mill, long (in alch.), from British Columbia (Keen). 



Mr. H. F. Wickham was so good as to send me some notes on the 

 Victoria slugs, as follows : " The very large slugs [^J.. columbianus 

 f. viactdatus'} from Victoria are found in the heavy woods on the 

 island in rather damp situations, especially around and in the cracks 

 of rotten logs. In damp weather I have seen them crawling around 

 on logs and on the ground. The little ones [P. pacijicuvi] from 

 Victoria also occur under logs, but I got them in much damper 

 places, especially under logs in ditches by the roadsides, and few or 

 none in the woods" (in Hit, Dec. 12, 1889.) 



LIST OF LAND AND FRESH-WATER MOLLUSCA COLLECTED 

 IN JAMAICA. 



BY C. W. JOHNSON .t WM. .1. FOX. 



The following is a list of the iiiollusca obtained on our recent trip 

 to Jamaica, during a part of Ajiril and June. As the species are 

 extremely local in there distribution, and our collecting confined to 

 the eastern part of the Island, and time largely occupied in collect- 

 ing insects, this list, represents but a small part of the Island 

 fauna. 



Collections were made near King.ston, Bogwalk in the Parish of 

 St. Catherine, Morant Bay, Manchioneal, Port Antonio, Hope Bay 

 and Swift River. At Kingston, Orthalicus undaius was abundant 

 on the trees, ascending to the height of ten or twelve feet ; as it was 

 very dry weather, they were all tightly closed with an epipliragm, 

 and so firmly attached to the bark that it required considerable force 

 to remove them. Helix invalida, Cylindrella hrevis and Tudora 

 armata were also numerous. Though the shells were quite jjlentiful 

 we did not succeed in finding a living Sagda Jayanus. At Port 

 Antonio, Tudora augustce, Cyclotus Portia ndiens is and Hyalosagda
