480 A COENISH FAtnSTA, 



Axius STIRYNOHUS. — Lsach, Malac. Brit. t. 33 ; Milne Edwards, 

 Sist. des Crust., t. ii, p. 311 ; Bell, Stalk-Eyed Crust., p. 228. 

 " The male of what I (Mr Couch) judge to be the same species, 

 differs from the female in the snout (rostrum), which in my 

 specimen of the latter was finely notched, and without the well 

 marked longitudinal ridge of the former. The outer antennae of 

 the male are furnished with a ridge of fine hair on their inward 

 line decreasing towards the point, which the female is without > 

 and the former also has well-marked brushes near the lateral edges 

 of the abdominal rings. This specimen, like those of the Genus 

 Callianassa, has the habit of burrowing in the sand, from which 

 it rarely emerges ; and then it seeks shelter in a crevice covered 

 with weeds, for it is sluggish in its motions, and if distant from 

 a soft bottom in which to sink, incapable of escaping an enemy. 

 A female that I obtained loaded with spawn, was dug out of sand 

 in the middle of summer. 



In the Zoologist for 1856, page 5282, Mr. Couch figured and 

 described a specimen that appears to differ from this only in the 

 more equal size of the two great chelae, and this might have been 

 due to a loss of one of the limbs and its gradual reconstruction. 



Gentjs, Gebia. — Leach. 



" Carapace terminating in a rostrum large enough to conceal the 

 eyes, the sides forming a ridge passing back and encircling the 

 region of the stomach. Outer antennae without a scale. Abdo- 

 men (Pleon) long, more enlarged behind ; caudal plates large. 

 The claw legs straightened, the moveable finger large, but not 

 met by a corresponding portion in opposition. The following legs 

 one fingered, those of the second pair having the next to the last 

 articulation large and ciliated." 



Gebia stellata. — Montagu; Leach, Malac, t. 31 ; Milne Edwards, 

 Hist, des Crust., t. ii,p. 313; Bell, Stalk-Eyed Crust., p. 223. 



The habits of this animal is similar to that of Callianassa, in 

 whose company it has been taken. Dr. Leach says that it has 

 been taken in Plymouth Sound under the mud, in which it makes 

 long winding horizontal passages, often a hundred feet or more 

 in length. 



Gebia DELTURA. — Lcttch, Malac, t. 31; Milne Edwards, Hist, des
