REPORT upon the CRINOIDEA, ASTEROIDEA, 

 ECHINOIDEA, and HOLOTHUROIDEA of the 

 L. M. B. C. DISTRICT.

This Report deals with all the groups of the Echinodermata 

 with the exception of the Ophiuroidea, which are discussed 

 in a separate paper by Mr. H. C. Chad wick (see p. 140). Most 

 of the species were obtained off the southern end of the Isle 

 of Man, where there is a rich and varied Echinoderm fauna. 

 In the immediate neighbourhood of Liverpool comparatively 

 few species were obtained, although some of them exist in 

 great profusion (e.g., Asterias ritbens at Hilbre Island). The 

 numbers of species to be recorded in the different Echino- 

 derm groups are as follows : — Crinoidea, 1 ; Asteroidea, 11 ; 

 Echinoidea, 6 ; Holothuroidea, 5. Mr. Chadwick (p. 140) 

 discusses six species of Ophiuroidea, making in all twenty- 

 nine Echinodermata. 



For previous records of occurrence I have made use of 

 Mr. Byerley's Fauna, Forbes' British Star Fishes, The 

 British Association Report upon Marine Zoology, and a 

 List compiled by the Isle of Man Natural History Society, in 

 1884. I have to thank my friend. Professor Jeffrey Bell, for 

 assistance in regard to the nomenclature and synonymy of 

 some of the species.
