BIBLIOGRAPHY. 7 



Pilsbry, H. A. — " The earliest publication of Dorcasia, Gray." Naut., 

 vol. ix., p. io8. 

 Mr. Pilsbry points out that this group was first described in 1S38, and 

 not in 1845, as usually supposed. 



Pilsbry, H. A. — " On the names of certain Subgenera of HcUcostyla." Naut., 

 vol. i.\., p. loS. 

 Dolichostyla and Opalliostyla are proposed to replace Prochihis and Eiuioxiis, 

 both of Albers and both preoccupied. 



Pilsbry, H. A. — " The Aulacopoda : a primary division of the Monotremate 

 Land Pulmonata." Naut., vol. ix., pp. 109-111. 

 A character such as the presence or absence of the pedal groove seems, 

 without further distinction, to be an insufficient ground on which to base the 

 creation of a " super-family "; and we fear that the criticism which Mr. 

 Pilsbry applies to those who have made use of the tail pore for the separation 

 of families will be shortly applied to his use of the pedal groove. 



Pilsbry, Henry A. — " Sculpture of the apical whorls, a new character for 

 distinguishing groups oi BuUmiiU." Naut., vol. ix., pp. 112-5. 

 Naturalists are at last becoming aware of the extreme importance of 

 the apical whorls in systematic work, as these are formed before external 

 influences have their full power, and we congratulate the author on his use of 

 the sculpture.

 pp. 49-112, pis. 17-31) ; ser. 2, part 38 (contains vol. x., pp. 49-96, pis. 

 16-25). Philadelphia, Nov., 1895. 



The present part in the marine series is almost entirely occupied with a 

 review of the genus usually known as Aplysia, but which Mr. Pilsbry replaces 

 by Tftliys, Linn., 1758 [non Linn. 1767, iiec auctores sequentes]. The point 

 on which this change turns, therefore, is whether the loth or 12th Edition of 

 Linne's work is to be the starting point, and general opinion now inclines to 

 the loth. It would seem to be a pity to have created a sub-family Aplysiinae, 

 as the use of Tetliys as a foundation for the name would be better. It must 

 be confessed that to the general student this entire group fails to attract and 

 has been much neglected, probably owing to the insignificant shell; we trust 

 that this work may stimulate their study. 



It is impossible to seriously criticise the work done in the land series — as 

 indeed it is in almost all the parts — owing to the fact that one sees but a small 

 portion of the work relating to the BuHiiii, without possessing the key to the 

 whole. Suffice it to say that this part concludes the study of Thaumastus and 

 contains the commencement of the review of the family Bulimulidae. In this 

 Mr. Pilsbry first considers the genus Plckocluilus, which he divides into 

 Plekochcilus s. ttr., having a wrinkled or malleate surface and a smooth spire, 

 and into Euiytiis, in which the shell is generally granulate or striate. The 

 first two pages of the genus Auris, Spix, conclude the part. 



The following are new species in the marine series; — Aglctja nuttalli (p. 50), 

 Tethys panamensis (p. 88), and T. rubertsi (p. 99).

 We decline to catalogue these supposed new species, all unfigured and 

 but briefly described in Latin, with in general no comparisons. This habitual 

 practice on the part of such distinguished authors is most strongly to be 

 reprobated.
