conspicuously large and dark eyes and in the less convex 

 palm and greater relative length of the prop, of the 

 gnathopods. From the latter the principal difference is 

 in the much shorter telson. The eyes also differentiate 

 it at once from A. tenuimanus, Boeck, and from A. 

 manudens, (Bate), with which I have found it associated. 

 From this species it is also distinguished by the rounded 

 lateral angle of the head, and by (as also from A . oculatus, 

 Hansen) the absence of the distal tooth on the anterior 

 margin of the prop, of the gnathopods. Males of this 

 species are scarce. Colour brown. Length 2J mm. 



Amphilochoides odontonyx (Boeck). 



8 m. "W. of Flesh wick Bay, 33 f., 5/6/92. Length 2 mm. 



Gitana sarsii, Boeck. 



Little Orme; Menai Straits, 5 to 10 f., 17/9/94; 8 m. 

 W. of Fleshwick Bay, 33 f. Length 2J mm. 



Gyproidia brevirostris, T. and A. Scott (Ann. and Mag. 

 N. H., 1893, Vol. XII., p. 244, PL XIII.). 



8 m. "W. of Fleshwick Bay, 33 f. Length 2 mm. Very 

 near C. damnoniensis (Stebbing) from which its most 

 obvious difference is the concave lower margin of the first 

 joint of the last perseopods. In C. damnoniensis the 

 lower margin is convex. 



Stenothoil\e. 



Stenothoe marina (Bate). 



Common from the mouth of the Dee to Menai Straits, 

 2 to 15 f . ; off Fleetwood and Blackcombe. Two speci- 

 mens 6 m. S.E. Calf of Man, 34 f., 25/4/95. Colour white 

 or stained with red especially about the head. Length 4 mm. 



Stenothoe monoculoides (Montagu). 



Abundant in tidal pools Port Erin, Fleshwick Bay, and 

 Port St. Mary, Isle of Man ; Menai Straits, April and May,
