the existence of individual species, and confines them to limited 
areas. 
Inachus leptochirus is with ova in November, thove we observed 
at that time being in an immature condition. The ova resemble 
those of the two preceding species, being spherical anda ich 
orange colour, becoming darker as the zoeew forms; the zo 
itself we have not yet seen. The swimmerets of the females of 
this genus are admirably adapted to protect the ova, and are, 
moreover, beautiful objects when examined by the microscope; 
they resemble very much the plumose antenne of the males of 
many of the Nocturni amongst the Lepidoptera; their position and 
duty in the economy of the animal is a most interesting one, and 
perhaps no other genus of British Crustacea than Inachus shows 
this remarkable development to such advantage.

OCCASIONAL NOTES. 
WILD CaT BREEDING IN CONFINEMENT.—In the review of Prof. Mivart’s 
work on ‘ The Cat’ (p. 269), Tam said to have “succeeded in getting the 
wild and domestic cat to breed together in confinement”; but this I cannot 
claim to have done, as I never even attempted to cross-breed from any of 
my Wild Cats. It was Mr. Pusey, of Pusey House, Berks (erroneously 
mentioned as in Oxfordshire in my letter in ‘The Zoologist’ for 1873, 
p- 8575), who bred several hybrids between the two animals, a handsome pair 
of which he presented to the Zoological Society, as I mentioned (loc. cit.). 
I can, however, claim to have ‘‘ascertained the curious fact (p. 270) that 
the period of gestation in the Wild Cat is sixty-eight days, or twelve days 
longer than the ordinary gestation of a tame cat”—a pair of Wild Cats in 
my possession having bred four consecutive years (1875—1878), the first 
two occasions being recorded in ‘The Zoologist’ for 1876. The litters 
consisted of three and two alternately —ALrrep HenxacE Cocks (Great 
Marlow, Bucks). 
SUPPOSED OCCURRENCE OF THE CRANK IN Co. DuBLIN: CORRECTION OF 
Error.—There is a strange alteration in my notice of the Crane at Howth 
(p- 259) which appears to have arisen from your having expanded my 
meaning beyond my intention. By ‘appendage to the tail” I intended to 
refer to the bushy, loose tail-coverts which collect over the rump in a large 
tuft or bunch, and are in themselyes sufficient to enable one to identify the
