did not recognize the large San Diego variety as Carpenteri, 

 though much like the shell figured, but referred it to rufocincta, 

 some of which are as large as the figure. 



It would please collectors here to find "jET. DupetitJwuarsi" ' 

 at all the localities given on p. 174, but we find it only at Mon- 

 terey. The authors seem to have confounded with it varieties of 

 jidelis and mormonum elsewhere, while Benicia and San Diego 

 must be mistakes in labeling by collectors. 



^''H. temcistnata," MS. name, p. 175, was unnecessarily pub- 

 lished, but the figure is useful as showing one of the fossil links 

 between Gfahhi and rufocincta, mentioned by me in vol. iv, pp. 

 218 and 235. 



^^H. facta,'' Newc. The fossil form only is figured, twice as 

 large as the living. 



"iT". [Euparypha) Tryoni, Newc," p. 178. This, of § D, as 

 shown by jaws and teeth, is not very distantly connected with 

 arrosa, of § C, while the type of Euparypha (pisana) has only 

 2 — 3 ribs (Albers) ! It otherwise resembles Arionta much more 

 nearly. The variations in the jaws of this species (ribs normally 

 6), as figured, are evidently imperfections, and cannot be taken 

 as invalidating their specific value. As far as I have examined, 

 the jaws furnish excellent specific differences even in species as 

 nearly allied as those of Arionta, § C. In Lysinoe, § A and B, 

 I find the jaw of mormonum closely resembling that of facta in 

 form and number of ribs (8). 



"^. (Ampelita) Rotvelli, Newc," p. 185, including Lohrii, 

 Gabb. I cannot believe that the resemblance of this to sepul- 

 cralis of Madagascar is more than analogical. Its true affinity 

 is as stated in vol. iv, p. 235, and in the preceding article. 

 {Sepuleralis is 3-banded.) 



^'' Succinea Oregonensis, Lea," p. 270, including " ^. Cfabbii, 

 Tryon." The figure looks too much Yike NuttaUiana on the pre- 

 ceding page, while it diff'ers entirely from Tryou's figure both of 

 this and of Gabbii. Tryon's figure agrees best with Oregonensis 

 of Lea, but on the other hand he gives a poor one o^rusticana, 

 Gld., of which Binney and Bland copy the original. Unfortunately 

 Lea's types do not seem to have been figured, unless Tryon used 

 them in preparing his work. 



'■^Zonites Neivberryayia, W. G. Binn.," p. 282. The reference 

 to this genus seems premature, the animal being unknown. Com- 

 parison with "Z. cultellata " opposite shows enough difference in 

 the shell to separate it, though probably it is not a 3IacrocycUs 

 either. 



Z. cultellata, Thorns., if really found in California, must have
