other things to the Bootle Free Museum, and have 
lately been placed in an excellent position where 
they have the advantage of a good light, and the 
Museum Committee kindly allowed Mr. Beasley to 
have them photographed. There is reason for 
believing that these are the original specimens 
described by Messrs. Cunningham and Yates and 
they are much finer than any thing that has been 
obtained of late years. The most important is one 
showing three impressions of the hind feet and two 
of the fore feet of the Chevrothertwm stortonense 
from Storeton, and may be compared with a some- 
what similar slab from Saxony. Mr. Beasley 
remarked on the apparent position of the hallux on 
the outer side of the foot of the Cheirotherium 
which might be accounted for by the feet being 
shehtly crossed in walking. 
2. Mr. Herbert C. Chadwick read a paper on the Hamel 
and Water-vascular Systems of the Asteroidea. 
(See ‘“‘ Transactions,” p. 231). The paper was 
illustrated by lantern slides. 
3. Mr. R. J. Harvey Gibson gave an interesting account 
of the Botanische Institut, Strassburg, and exhibit- 
ed photographs of the buildings. 
4. Prof. Herdman laid on the table the Report of the 
work done in the Fisheries Laboratory for the year 
1892. (See “‘ Transactions,” p. 100). 
The seventh meeting of the Society was held at Univer- 
sity College on Friday, 14th April, 1893, Mr. A. O. Walker, 
President, in the chair. 
1. Miss F. Phillips exhibited with a description, specimens 
and drawings of Alpheus affins, and Palinwrus 
vulgaris, showing the structure of the sound pro- 
ducing organs of these Crustacea.
