UPOGEBIA BROUGHT TO LIGHT 185 
Upogebia, Leach, 1814, was founded to receive another 
species discovered by the industrious Montagu, and de- 
scribed by him in 1805 (1808) as Cancer Astacus stellatus. 
The colour, he says, is ‘yellowish-white, covered with 
minute stellated orange spots, as it appears under a lens, 
which give a predominance to the last.’ In this genus 
the first pair of legs are subequal and subchelate, the 
other pairs being simple; the second pair of pleopods is 
like the three following pairs, with the margins strongly 
ciliated ; the components of the swimming fan are broad- 
ended. It seems to have escaped the notice of writers sub- 
sequent to Leach that the earliest name of this genus was 
Upogelia, which must therefore be retained in preference 
to Leach’s own alteration of it into Gebia, or Risso’s Gebzos. 
Bell refers to the ‘ Edin. Encycl., xi. p. 400,’ as an authority 
for Gebia stellata, printing xi. by mistake for vu., and 
probably guessing at Gebia by mistake for the actual 
Upogebia. 
The type species was taken along with the type of 
Callianassa. On the nearly allied American species de- 
scribed by Say, Verrill and Smith make the following 
observations :—‘ The Gebia affinis is a crustacean somewhat 
resembling a young lobster three or four inches in length. 
It lives on muddy shores and digs deep burrows near low- 
water mark, in the tenacious mud or clay, especially where 
there are decaying sea-weeds buried beneath the surface. 
The burrows are roundish, half an inch to an inch in 
diameter, very smooth within, and go down obliquely for 
the distance of one or two feet, and then run off laterally 
or downward, in almost every direction, to the depth of 
two or three feet, and are usually quite crooked and wind- 
ing. We have found them most abundant on the shore of 
Great Egg Harbour, New Jersey, near Beesley’s Point, 
but they also occur at New Haven and Wood’s Hole, &c. 
This species is quite active; it swims rapidly and jumps 
back energetically. It is eagerly devoured by such fishes 
as are able to capture it. When living the colors are 
quite elegant. Along the back there is a broad band of 
mottled, reddish brown, which is contracted on the next to
