410 Woods : Marine Biology at Redcar. 



twenty coral polypes of a light yellowish-brown colour, each 

 projecting from a ribbed calcareous corallum of perfect white- 

 ness. Each corallum was made up of ten or twelve ribs. I 

 cannot name this, though it may belong to the Caryophyllia 

 smiihii. 



On the under sides of large stones, and on sides of cavernous 

 rocks I found fairly thick masses of the compound ascidian, 

 Botryllus smaragdus, and doubtless other varieties are to be 

 found. There were also specimens of Cynthia aggregata, 

 another ascidian. 



Sponges were fairly common, but I only noted — 



Halichondria panicea. \ Grantia compressa. \ Halisavca.

The chief value of the meeting did not consist, however, in 

 the records of various species, but in the local interest which 

 it excited. Many residents, especially school teachers, visited 

 the collection which was made and arranged in order, and will 

 carry on their study for themselves. A hope was expressed 

 that Scarborough would be visited next year. 



A List of British Birds, by Mr, W. R. Ogilvie-Grant (Witherby & Co., 

 326 High Holborn, W.C, 1/6), will be found most useful to ornithologists. 

 It is brought up to date, and shews at a glance the exact status of each 

 species. It also gives, in a most concise form, the information under heads, 

 as to whether a resident breeding species, a summer visitor breeding, an 

 autumn, winter, or spring visitor now breeding, occasional visitor used to 

 breed, and occasional visitor never having been known to breed. It is 

 printed only on one side of each page, and can thus be of great use for 

 labelling specimens. The printing and paper are of good quality.
