THE NAUTILDS. 1 19 



pressed keel along sutures and at the periphery ; subper- 

 forate ; aperture lunar, oblique, a little contracted; finely 

 rib-striate above and below. Alt. 2, diam. 4 mm. Haha- 

 jima (Ilirase, no. 801). H. nesiotica, n. sp. 



A third form was sent from Chichijima, Ogasawara (no. 800), 

 similar to H. nesiotica, but much smaller, diam. 3.2 mm., with 

 barely 4 whorls. This may be called H. chickijiinana. Subse- 

 quently some five additional new species from Hahajima have been 

 received. 



GENERAL NOTES. 



HELIX ASFEKSA INCREASING IN CALIFORNIA. Complaints are 

 being made that the spotted snail, Helix as-persa, is becoming too 

 common in the gardens of San Jose, Oakland and Los Angeles, 

 California, and that it is injuring many flowers and vegetables. 

 This species was introduced into California from Europe many years 

 ago, presumably by a Frenchman who considered it a choice delicacy 

 for his table. For a long time the snails were confined to a small 

 plot of ground in the city of San Jose, but of late they have evidently 

 resolved upon a " policy of expansion," and are spreading rapidly 

 and are liable to cause serious mischief. It is to be hoped that Cali- 

 fornians will cultivate the French taste and thus turn the tables on 

 the molluscan invaders JOSIAH KEEP. 



TRUNCATELLA SUBCYLINDRICA Linnauis. 



This species has been credited to the West Indies by various 

 writers, even to the present time, although Linnaeus and all the 

 early English authors gave it as a species of Europe. Ball and 

 Simpson, in their Mollusca of Porto Rico, 1901, Bull. Fish Com- 

 mission, p. 436, give its range as " Porto Rico; adventitious in 

 England; common in Florida and many localities in the West 

 Indies." 



The Linnrean species is in fact a common European shell, occur- 

 ring as far north as England ; thinner, more transparent, and typic- 

 ally smoother, than any Antillean Truncatella. It is commonly 

 found in older collections under the name T. montayui, and is prob- 

 ably not specifically distinct from T. truncatula Drap. The "T.sub- 

 cylindrica Gray" of Binney's Terr. Moll, iv, and Land and F. W.
