GENUS CRANGON : Carapace somewhat depressed, with 
only the rudiment of a rostrum, antennas inserted on about 
the same transverse line, on the outer side a large scale. 
The claw legs expanded, the moveable finger opposed to a 
slight rudiment of a process. 
Sand SHRIMP. C. Vulgaris. M. Edwards’ Crust., vol. 
2, p. 341. Leach’s Malac. pi. 37. Astacus C. Pennant, 
pi. 15. fig. 30. 
Common in harbours on a sandy bottom, in which it buries 
'tself ; an operation performed by the aid of the hinder legs, 
but it heaps the loose sand on itself by the action of the 
a ntenn3e. 
Rough SAND SHRIMP. C. Cataphractus. M. Ed- 
wards’ Crust., vol. 2, p. 343, Pontophilus Spinosus, 
Leach’s Malac. pi. 37. 
I have possessed only one specimen, which came from the 
stomach of a fish takeu at a depth of from 12 to 15 fathoms. 
GENUS AUTONOMEA: eyes on short footstalks, project- 
ing from beneath the border of the carapace. 1 he snout 
scarcely passing beyond the eyes. The inner antennas 
double, one filament much longer than the other. Outer 
antennso slender, and much longer than the body, hirst 
pair of legs only with hands. 
LONG HORNED SHRIMP. A. OHvU. M. Edwards’ 
Crust., vol. 2, p. 361. _ _ 
This species has been hitherto unknown as British, but I 
nave examined several specimens taken from the stomachs of 
fishes from the depth of 15 or 20 fathoms. Some of these 
Were of larger size than described from the Mediterranean : 
°ne, not the largest measuring 3 inches from snout to tail, 
With antennas of the length of 5 inches. 
GENUS B1PPOLYTE : Carapace inflated on the top ; ros- 
trum large, compressed, toothed. 
BRANCH’S HIPPOLYTE. B. Cranclni M. Edwards 
Crust., vol. 2, p. 376. Leach’s Malac., pi. 38. 
Common in crab boats, and consequently living where the 
fishery is carried on for Lobsters. 
GENUS PANBALUS: The two first legs single fingered, 
the second pair slender and with a minute finger. Rostrum 
long, elevated towards the end, and toothed above and 
below. 
LONG SNOUTED SHRIMP. P. Annulicornis. M. Ed- 
wards’ Crust., vol. 2, p. 384. Common in crab boats. 
There appear to be two other species of this minute genus 
our coasts ; which I have been accustomed to call iEsop 
Shrimps, from their habit of bending up the back into an 
,, Urn P ; but further observation is necessary to decide whether 
b e y are known to Naturalists.
