A HISTORY OF DEVONSHIRE 



station. I have endeavoured to indicate generally the sources from which information and verifica- 

 tion may be obtained, and I may be permitted to explain that, for the great tribe of the Gam- 

 maridea, the arrangement and nomenclature are followred which will appear in the Amphipoda of 

 Das Tierreich. 



Sub-class LEPTOSTRACA 



Family Nebaliidae 



Nebalia bipes (O. Fabricius). Cancer b., O. Fabri- 

 cius ; Monocultts rostratus, Montagu ; ' 'Nebalia 

 HerbstU, Leach ; N. Montagui, Thompson ; 

 N. bipes, KrOyer, Baird, Sars, Allen. This 

 species which, among other places,' occurs on 

 the shore at Salcombe, was long the only 

 known representative of this sub-class. Its 

 position in classification is still in dispute. The 

 accessions to our knowledge will be found well 

 discussed in ' Die Leptostraken,' by Dr. Joh. 

 Thiele' 



Sub-class ENTOMOSTRACA 



Order Branchiopoda 



Sub-order Phyllopoda 



Family Branchipodidae 



Chirocephalus diaphanus, Prevost. Mr. A. K. 

 Coomaraswamy, F.L.S., has favoured me with 

 the following records for the occurrence of the 

 ' Fairy Shrimp ' in Devonshire, from Mr. F. J. 

 Partridge of Barnstaple, who found it 'in a 

 small roadside pool, which is dry in the hot 

 season, between Braunton and Saunton, N. 

 Devon, in the spring season of 1900 ; also in 

 the same kind of pool between Morte Station 

 and Lee, near Ilfracombe, very numerous at 

 Christmas, 1 901, a thin sheet of ice over the 

 pool.' The species has been found in Surrey 

 also at Christmas-tide under ice 



Sub-order Cladocera 



Tribe Onychopoda 



Family Polyphemidae 



Evadne nordmanni, Lov6n. Observed at the Ply- 

 mouth station from March to October ; carry- 

 ing ova in August (Hodgson) ; winter eggs 

 produced about mid-September (E. J. Bles) 

 Podon intermedius, Liljeborg. Plymouth neigh- 

 bourhood, April to September ; carrying ova 

 in August (Hodgson) 

 — leuckarti, Sars. Plymouth neighbourhood, April 

 1904, rare (L. H. Gough) 

 This sub-order comprises two sections, the Calyp- 

 tomera and Gymnomera, the latter divided into two 

 tribes, the Onychopoda and Hapfopoda, the former 

 also into two tribes, the Ctenopoda and Anomopoda. 

 In the work just published by Dr. Norman and 

 Dr. T. Scott on the Crustacea of Devon and Corn- 

 wall, between twenty and thirty species of Calyp- 

 tomera have been recorded for Devonshire, most of 

 them forms well known and widely distributed.
