3. Note on the Solid-hoofed Pigs in the Society’s Collection. 
By A. H. Garrop, F.R.S., Prosector to the Society. 
On November 2nd, 1876, there arrived in the Gardens a pair of 
Pigs (domestic variety) presented to the Society by Don J. Alfonso 
de Aldama, from Cuba, peculiar in that the hoofs of all the feet, 
instead of being cloven, are solid, much resembling those of the Ass, 
with the lateral diminutive digits as they are always found in the 
Pig. 
The sow gave birth on November 15th to a litter of six, three 
males and three females. Of these the hoofs were solid (like those 
in the parents) in three, namely in two males and one female. In 
the remaining male and two females the hoofs were double, as in the 
animal under ordinary circumstances. 
Four of the young pigs are now living (a pair of solid-hoofed and 
a pair of normal-hoofed), a male solid-hoofed and a female split- 
hoofed specimen having died within a few days of birth. 
On examining the feet of the deceased male solid-hoofed specimen, 
it was seen, as might have been inferred from an inspection of 
the living animals, that all the monstrosity is confined to the ungual 
phalanges. The proximal and second phalanges are separated as 
usual, whilst at the extreme distal ends of the ungual phalanges these 
bones are completely fused together; and, further, there is a third 
ossicle developed at their proximal ends, where they are not com- 
pletely united, between and above them. 
It might have been imagined that the deformity was simply the 
result of an agglutination along the middle line of the two com- 
pletely formed digits ; but such is not the case, the nail-structure 
being absent in the interval, where it is replaced by bone with a 
transverse cartilage below it. The nail is continued straight across 
the middle line of the hoof, as in the horse. In Mr. Darwin’s 
‘Animals and Plants under Domestication’ (ed. 2, vol. i. p. 78), a 
full account will be found of several cases in which an exactly similar 
deformity existed.

Hexix (RaAGADA) KOORINGENSIS, 0. sp. 
Shell umbilicated, somewhat globosely lenticular, rather thin,

less elevated and irregular, the interstices crossed with short, im- 
pressed, interrupted, transverse lines, especially on the basal portion 
of the last whorl, cretaceous, white; spire flatly conoidal, apex 
obtuse, sutures impressed; whorls 5, slightly convex, the last very
