( = Pycnogonida) of the Temperate Atlantic and Arctic Oceans,'" ^ 

 in which 32 species — a number of them abvssal forms — are 

 recorded for the "British Area."" Adopting the nomenclature 

 and synonymy of this Catalogue our Forth list stands thus : — 



Phoxichilidium femoratum (Rathke). 



Anaphia petiolata (Kjroy.). 



Pallene hrevirostris, Johnst. 



Phoxichilus circularis (Goodsir). 



Xymphon ruhrum, Hodge iX. gracile, Johnst. nec Leach). 



N. hrevirostre, Hodge {X. gracile, Sars). 



X. grossipes, Fabricius. 



X. gracile, Leach (X. gaUicum, Hoek). 



Chcetonymphon hirtnm (0. Fab.) {X. spinosurn, Goods., nec Sars). 

 Pycnogonum littorale, Strom. 



CEUSTACEA. 



Of this important section of the Arthropoda our knowledge 

 is very full and up to date, thanks mainly to the industry 

 and skill of Thomas Scott, LL.D., F.L.S., who has for many 

 years made the subject his own. Dr Scott's " Catalogue of 

 Land, Fresh-Water, and Marine Crustacea found in the Basin 

 of the Piiver Forth and its Estuary," recently laid before 

 this Society,- is a valuable piece of work, and the author 

 is to be congratulated on its completion. It includes in all 

 no less than 796 species. In course of time further dis- 

 coveries will no doubt be made, but there seems little reason 

 to suppose that the number of Forth Crustacea can exceed 

 850 or thereby. 



In his capacity of naturalist to the Fishery Board for 

 Scotland, Dr Scott has had, during the past twenty years, 

 unrivalled opportunities for investigating the Crustacean 

 fauna of the area, and he has certainly made ftiU use of 

 them. The foundations of the Catalogue were, of course, 

 laid long before Dr Scott's investigations began, by Sibbald, 

 Jameson, Leach, H. Goodsir,^ J. Anderson, Howden, M'Bain, 

 and others, but their observations were practically confined 

 to the larger forms, i.e., to the Malacostraca and Cirripedia. 

 A good many species were added to the list from the mouth
