young of intcrtcxtus are strongly angulated and those of V. vivipanis are 

 quite acutely carinated the distinction does not seem to he well taken. If, 

 however, for any valid reason, it should be found desirable hereafter to 

 separate the two groups, the name will be available. 



X'lviPAKA LiNKATA ( X'alencienncs) . 



W. G. Jiinney (13, p. 295 j from an examination of the type states that 

 this is the J', bcngalcnsis (Lam.) from India. 



\'ivirARus MAi.ivKATus Rccve. 



This Japanese species has been introduced into a number of localities 

 on the Pacific coast and has been listed under various names : — 

 Paliidina japonica Wood, Naut., V, 1892, p. 114; Ibid, VI, 1892, p. 51. 

 Vivipara steUnaphora Stearns, Naut., XV, 1901, p. 91. 

 Vivipara lecythoides Hannibal, Naut., XXII, 1908, p. 33. 

 Jlvipariis malleatiis Hannibal, Naut., XXV, 191 1, p. 31. 



Hannibal (53, p. 194) has made this species the type of a new subgenus, 

 Cipaugopalndina, which he refers to Idioporua Pils., (98, p. 189) originally 

 proposed as a subgenus, but which he raises to generic rank. As the valid- 

 ity of both of these changes must be ultimately determined by a study of the 

 Asiatic species, they may well be held in abeyance until that has been done. 



ViviPARUs jAPONicus V. Martens. 



This species has been introduced into British Columbia (Pilsbry and 

 Johnson, no, p. 144) and California (Hannibal, 52, p. 32). 



It has also recently appeared in the ^luddy River, Brookline. Mass. 

 (Johnson. 60, p. 35 and 61, p. 48). 



Hannibal (53, p. T94) refers it to Idiopoiua Pils. 



VivAPARA MUL/i'iCARiNATA (Haldcman). 



This name was proposed by Haldeman for the Paliidina carlnata Val., 

 which was erroneously stated by the author to be from jMexico, carinata 

 having already been used by Swainson for an Indian species of the same 

 genus. W. G. Binney (12, p. 430), states that the types in the Jardin des 

 Plantes, Paris, are labelled in Valenciennes' handwriting "Philippines." It 

 is undoubtedly a form of V. biirroiigJiiaiius' hea.
