clared it to be a mere color variety of H. subconica C. B. Ad., de- 
scribed in 1845, and the figure he gives of his type amply confirms 
this opinion. In the Conchylien Cabinet, a few pages further on, 
Pfeiffer describes and figures a “ Helix gossei C. B. Adams MSS.” 
This name, of course, cannot stand, being preoccupied by that prior 
H. gossei of Pfeiffer himself, and this decision is not affected by the 
fact that Pfeiffer’s first gossei isasynonym. This gossei of (C. B. 
Ad.) Pfr., I consider a race or variety of H. nemoraloides C. B. Ad., 
1845, and it is practically covered by C. B. Adams’ H. pulchrior, 
1851. It is this form which caused Messrs. Simpson and Hender- 
son some trouble in Naurrius for May, 1894, p.5. The conclu- 
sion is that neither of the “ gosseis” can stand, the first gosset of 
Pfr. being a synonym of subconica, and gossei C. B. Ad. MS. of Pfr. 
(later) becoming a synonym of H. nemoraloides var. pulchrior.—

HELICES CARRIED BY BIRDS.—“ From the throat of Rallus pee- 
toralis Mr. J. A. Thorpe of the Australian Museum extracted the 
snail I now exhibit. This is a specimen of Ch/oritis jervisensis 
(uoy and Gaimard, a species common in this neighborhood, whose 
almost adult and uninjured shell measures 18 mm. in diameter, and 
which weighed, shell and animal together, 1°26 grammes. When 
found by Mr. Thorpe, to whom I am indebted for both facts and 
specimen, the snail was quite dead; asa test I immersed the ani- 
mal in strong spirits without inducing contraction ; since, however, 
its consumer had been killed forty hours earlier, the suffocation of 
the molluse was to be expected. The bird was shot at Randwick, 
near Sydney, on the 19th May, 1894, by Mr. Newcombe, Deputy 
Registrar-General. In enumerating “ Means of Dispersal,” Dar- 
win observes (Origin of Species, 6th ed. p. 372): ‘A bird in this 
interval [eighteen hours] might easily be blown to the distance of 
500 miles, and hawks are known to look out for tired birds, and 
the contents of their torn crops might thus readily get scattered.’ 
In view of the above incident, this suggests a means whereby the 
geographical range of jervisensis might be considerably extended.”
