THE MARINE BIOLO(iTCAL ASSOCIATIOX OF WEST OF SCOTLAND. 309 

 As mentioned in my interim report, two new species were discovered, 



VIZ. : — 



Plenrocrypta Paticiicel, Scott. P. Cliitha; Scott. 



They have been described by Bv. Thomas Scott, F.L.S., of H.M. 

 Fishery Board, in a paper contributed to the ' Ann. Mag. of Natural 

 History.' 



I have reason to believe that a Sacculina which I discovered on 

 Munida rnc/osa, Fabr., as also one on Galathea intermedia, Lillj., and a 

 Feltogaster on Anajmgurus Icevis, Thomp., are new to science. I am 

 waiting, however, for further material to establish this fact. 



The following species which I have discovered are new to the Clyde 

 sea-area, viz. : — ■ 



Decapoda. 



Ebalia CostfP, Heller. 



E. Ciisfa, Heller, var. granulosa, Milne-Edw. 



I am indebted to Dr. Norman, F.R.S., for identifying the above. 

 I have verified Landsborough Martin's record of the occurrence in Clyde 

 waters of E. Cranchii, Leach, which was held as doubtful by Dr. J. R. 

 Henderson.^ 



Xanthd /it/droj)JiUus, Herbst., var. tulcreulata, Couch. 



I have established the occurrence, at the greatest depth (107 fathoms), 

 within the Clyde sea-area, of Pandahis Montagui, Leach. Records of 

 its occurrence in depths of over 70 fathoms in British waters have hitherto 

 been regarded with doubt. - 



Schizopoda. 

 Macrojnts Slahheri (Van Beneden). Pneudomma roseum, G. O. Sars. 



I have contributed two papers to the Glasgow Natural History Society 

 of Glasgow dealing with the occurrence of the two above-named Schizo- 

 pods within the Clyde sea-area. 



Isopoda. 

 Idothea netjlecta. G. O. Sais. I. viridis (Slabber). 



I am of opinion that these two species have been confounded by 

 previous observers in the Clyde with /. haltica (Pallas). 



I submitted them to Dr. Scott, who agrees with my identification of 

 them. 



Eiinjdice spinigcra, H. J. Hansen. Cymodocc truncata. Leach. 



I believe this species, as well as C. emarginata. Leach, were recorded 

 by the late Dr. Robertson, Millport, but have been inadvertently omitted 

 from Dr. Scott's list. 



Plcitrocrypta lonqihrancldata (B. & W.) on Galathea dlspersa, Bate ; and on 

 G. sqiiawifera, Leach.
