ZOOLOGY or FERNANDO NORONIIA,

It corresponds closely to the figure given by Humbert, excepting 
that it is only 10 millim. in length instead of 22 millim., and 
that the antennae are as hispid as those of I. solifuga, Halliday. 
In Humbert’s figure the antennae are quite glabrous, hut as he 
does not mention this among the differences between his species 
and I. solifuga , it is possibly an error of the draughtsman. The 
number of joints in the antennae is almost equal to that of 
I. Saussurii , and more than that of I. solifuga • but the animal 
is but little larger than the type specimens of I. solifuga in the 
British Museum. Another point of difference, though very 
slight, is in the forceps. In both the above quoted species there 
is a secondary tooth on the inner edge of each chela, besides 
several smaller rounded papillae ; now in the specimen from 
Bern an do Noronha this secondary tooth is nearer the apex 
of the chela than is either of the others. 
Distribution. The distribution of the whole genus is very little 
known at present, as specimens are not often collected. I. soli- 
fuga occurs in South Europe, Algeria, and Madeira (the var. 
WoTlastoni). I. Saussurii was obtained in Mexico at Orizaba. 
Species are also recorded, but not described, from the United 
States and Calcutta. 
Dr. Grassi, in p. 1 of “ Progenitori degli Insetti e dei Miria- 
podi,” gives I. Saussurii as from Brazil ; but does not say whether 
he has seen Brazilian specimens ; and in his list of species mentions 
it merely from Mexico, evidently using “ Brasili ” as a synonym 
for Mexico. It is more than probable that, if sought fox’, it will 
be found to occur also on the mainland of Brazil. 
Lepisma Leal, n. sp. 
Though it was to be expected that house-inhabiting Lepismas 
would occur here, I sought for them in vain until just as we were 
leaving, when a single large Lepisma , perhaps distui’bed by the 
packing-operations, appeared. The specimen was somewhat 
damaged in eaptui’ing it ; but as it seems to be undescribed, and 
is a very curious animal, I describe it as it is.
