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 



itself; an operation performed by the aid of the hinder legs, 



but it heaps the loose sand on itself by the action of the 



antenna?. 



ROUGH SAND SHRIMP. C. Catapkractus. 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 taken at a depth of from 12 to 15 fathoms. 



GENUS A UTONOMEA : eyes on short footstalks, project- 

 ing from beneath the border of the carapace. The snout 

 scarcely passing beyond the eyes. The inner antennae 

 double, one filament much longer than the other. Outer 

 antennae slender, and much longer than the body. First 

 pair of legs only with hands. 



LONG HORNED SHRIMP. A. Olivii. M. Edwards' 

 Crust., vol. 2, p. 361. 

 This species has been hitherto unknown as British, but I 



have 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 : 



one, not the largest measuring 3 inches from snout to tail, 



with antennae of the length of 5 inches. 



GENUS HIPPOLYTE-. Carapace inflated on the top ; ros- 

 trum large, compressed, toothed. 



CRANCH'S HIPPOLYTE. H. Cranchii 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 PANDALUS: 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. Anmdicornis. M. Ed- 

 wards' Crust., vol. 2, p. 384. Common in crab boats. 

 There appear to be two other species of this minute genus 



on our coasts ; which I have been accustomed to call iEsop 



Shrimps, from their habit of bending up the back into an 



hump ; but further observation is necessary to decide whether 



they are known to Naturalists,
