HIGHER CRUSTACEA OF THE FIRTH OF CLYDE. 337 



Eupagurus cuanensis, Stinipson, Proc. Acad. Nat. Sc. Phil., 

 1858, p 75. 



Lamlash Bay and C umbrae (Norman). In the 

 upper laminarian zone Clachland Point, and dredged 

 in Lamlash Bay (Herdman). We dredged it in shal- 

 low water off Portin cross, off Cumbrae, and on the 

 Skelmorlie Bank, but it does not appear to be a very 

 common species in the Clyde. 



Genus Spiropagurus, Stimpson. 

 Spiropagurus, Stimpson, Proc. Acad. Nat. Sc. Phil., 1858, p. 74. 



Subgenus A nap A GURUS, no v. 



Carapace depressed in front, the transverse su- 

 tiu'e very deep. Ocular peduncles short and stout, 

 the cornese dilated. Chelij)edes unequal, the right 

 larger. External antennae with long slender 

 flagella which are usually ciliated, the acicle 

 slender. Ambulatory legs long and slender. Males 

 furnished with a short curved genital appendage 

 attached to the coxa of the fifth left leg. 



It differs from Spiropagurus in the form of the 

 male sexual ai)peiidage, which is spirally coiled in 

 the latter, and in the unequal chelipedes. In Sj^iro- 

 pagurus, also, the ambulatory limbs, especially their 

 meral joints, are more robust, and the dactyli are 

 proportionately longer and ciliated. The external 

 maxillipedes are also much shorter in Anapagurns. 

 It is allied to Catapagurus, A. M. Edw. ( = Hemi- 

 pagiirus, S. I. Smith), but in this genus the male 

 appendage is attached to the coxa of the fifth right 

 leg. 



In the writer s forthcoming rej)ort on the " Chal- 

 lenger" Anomura, this subgenus will be more fully 

 characterised, and new si)ecies described from the 

 Canary Is., Cape of Good Ho]3e, and Port-Jackson.
