which records the discovery of several interesting novelties 

 and the transference of a species of Lafoca to another genus 

 {Galycella pigmcea) . 



Ed., L.M.B.C. Kepts. 



In the last report on the Hydroid Zoophytes, in 1886, 63 

 species were recorded as having been found in Liverpool 

 Bay. Two species, Thuiaria thuja and Aglaopheiiia pen- 

 natula, might have been added from Mr. Charles H. 

 Brown's list given in " The Handbook for Southport," 

 edited by Dr. E. D. McNicoll, 1861. 



Since then (1886) four species : — Tiihularia attenuata, 

 Campanularia rariclentata, Halecium muricatum, and 

 Bertularella tenella have been recorded by Mr. G. W. 

 Wood in Volume III of the Fauna of Liverpool Bay ; and 

 eighteen I have identified from material sent to me from 

 time to time after dredging trips and shore collections had 

 been made, these are : — Coryne van-henedeni, Hydranthea 

 margarica, Bougainvillia ramosa, Ohelia plicata, Cam- 

 panularia fragilis , Gonothyrcea gracilis, G. hyalina, Lafoea 

 fruticosa, Galycella fastigiata, G. pigmcea, Guspidella 

 grandis, G. costata, G. humilis, Sertiilarella gayi, S.fusi- 

 formis, Aglaophenia tuhulifera, Plumulariafrutescens, and 

 P. echinulata. To these the following 12 (Eudendriiim 

 rameum, Bimeria vestita, Tuhularia larynx, Ohelia genicu- 

 lata, Opercular ella lacerata, Filellum serpens, Diphasia 

 pinaster, Thuiaria articulata, Aglaophenia myriophtjllum, 

 Flumularia setacea, P. catharina, and P. similis) may be 

 added as new to the L.M.B.C. although they have already 

 been reported in "Fauna" Vol. I., as having been found 

 in the district by earlier collectors. This makes 36 addi- 

 tional species in all (and there is also the variety Lafoea 

 dumosa var. rohusta) which are new to us since 1886, and
