HYDROIDS 



The principal contributors to our knowledge of the county representatives of this fascinating 

 group have been R. Q. Couch, Peach, Cocks, and Hincks. The observations of the first-named 

 are recorded at some length in (Jonathan) Couch's Cornish Fauna, pt. 2 (1841); Peach published 

 his notes in the Journal of the Royal Institution of Cornwall (1849 and 1878) ; while those of Cocks 

 appeared in his 'Cornish Fauna' (Seventeenth Ann. Rep. Roy. Cornw. Polyt. Sac. 1849). From the 

 time of Peach's last paper the group has been somewhat neglected, but of recent years Vallentin has 

 paid some attention to the species of the Falmouth district. E. T. Browne has published some obser- 

 vations on the occurrence of Medusa stages at Scilly, and excellent work has been done around 

 Plymouth.
