The following is a classitied list of the species of Crustacea 

 captureil by Mr. Holt ami arranged in the ortler in which 

 they arc rcterrcd to above. 



Suborder D E C A i' o D A. 

 Crangon AUmanni, Kinaiian. 



Cram/on Alhnanni, Kiiialian, Proc. Dublin Nat. Hist. Soc. vol. iv. p. 80 

 (l«o7). 



This species aj)pears to be usually confined to off-shore 

 ■\raters, and may lie distinguished from Crangon vulgaris not 

 only by its colour when alive, but also by the abdomen 

 liaving posteriorly a distinct median dorsal groove. Crangon 

 AUmnnni frequently forms an imjjortant part of the food of 

 the haddock and the cod. 



Crangon namis^ Kroyer. 



Crangon nanus, Kroyer, Naturliistorisk Tidsskrift, ser. 1, vol. iv. p. 231 

 (1^42). 



This appears to be the Crangon bispinosa, Bell (Brit. 

 Stalk-eyed Crust, p. 268, 1853), and seems to have a fairly 

 wide distribution in British waters. It is, as its name implies, 

 one of the smaller species of Crangon. 



Pandalus anyiuUcornisy Leach. 



Pandalus annulicornis, Leacb, Malao. lirit. t. xl. ; Bell, Brit. Stalk- 

 eyed Crust, p. 297. 



This is one of the most valuable of the smaller Crustacea for 

 food purpo;es. A regular and remunerative fishery of the 

 " prawn " and the " common shrimp " is carried on at several 

 places round the British coasts. The larger food-fishes also 

 prey frequently on Pandalus annulicornis^ the fragments of 

 these Crustaceans often forming a large portion of the contents 

 of the stomaclis of such fishes. It appeared to be scarce at the 

 south-west end of the Dogger Bank at the time the present tow- 

 net gathering was collected. 



Suborder S C ii i z r D A *. 



Gastrosaccus spinifer (Goes). 



Mysis spinifera, Goes, Crust, decapoda podoph. marina Succi.-c, p. 14 

 (18G3). 



(1886) ; Rev. A. M. Norman, " On a Crangon, some Schizopoda, and 

 Cumacea new to or rare in the Britisli Seas."
