1. MOKSTEILLA ANGLICA, 



Monstrilla anglica, Lubbock. On Eight New Species of Ento 

 mostraca taken at Weymouth (Ann. and 

 Mag. Nat. Hist., vol. xx, 2nd series, pi. x, 



figs. 7, 8, 1857). 



Of this Copepod I know nothing except from the 

 description referred to above, the specimen itself 

 being unfortunately lost or mislaid. The following is 

 Sir John Lubbock's description of the animal : 

 " Frons quadrata, angulis rotundatis. Cephalothoracis 

 segmentum primum postice paullo latius. Antennas 

 5-articulatee, setis antenna brevioribus. Abdomen 

 4-articulatum, segmentis subasqualibus. Styli caudales 

 oblongi, divaricati, setis 6-suba3quis, diffusis.
