HIGHER CRUSTACEA OF THE FIRTH OF CLYDE. 353 



Doubtful Clyde Species. 

 The presence of the following species in the Firth 

 of Clyde requires further confirmation, and the 

 grounds on which they have been admitted are not 

 altogether satisfactory. One or two, at least, may 

 be the result of an error in identification. 

 Maia sqninado (Herbst). 

 Achaeus Cranchii (Leach). 

 Gonoplax angidata (Fabr.). 

 Ehalia Cranchii (Leach). 

 Palaemonetes varians (Leach). 

 Since the earlier i3art of the paper was Avritten 

 ^ve have seen a specimen of Pi rime! a denticulata 

 {Mont.), dredged by Mr. A. Somerville of Glasgow, 

 in Gair Loch, West Ross-shire, a species unrecorded 

 in our list of West Coast Crustacea. 



The Rev. Dr. Norman, in a recently published list 

 of the North Atlantic and Arctic Crustacea in liis 

 private collection (March, 1886), makes the following 

 species synonymous :— 



Pagui'us fen-ugirieus, Norman, = Spii'oj^aguriis 

 ( Aiiapagui'us) chiroacantJuis (Lilljeborg). 



Hippohjte cnltcUata, Norman, = H. j^olaris (Sabine). 

 My sis Griffithsiae, Bell, = Siriella armata, M. Edw. 

 The latter names having priority must therefore be 

 adopted. 



Dr. Norman also names a new schizopod from 

 the Clyde:— 



Siriella Brooki, Norman. 

 Zostera-bed at low-water, Tarbert (Brook).
