notice that the feathers at the base of the upper mandible showed 

 no marks of the abrasion usual in the Kook, while those at the 

 base of the lower mandible were partly destroyed, although not to 

 the same extent as is found in specimens where the bill is jproperly 

 developed. 



Mr Peter Cameron stated that he had found, in a gall of Nematus 

 viminalis. a very young larva of Pimijla graminellae, without there 

 being any trace of the saw-fly larva. The young PimiJla larva 

 continued to grow, and arrived at maturity by feeding on the 

 juices of the gall, this being a deviation from the usual habits of 

 the Ichneumons, which are, as a rule, animal feeders. Mr 

 Cameron's observations confirmed those of Dr Giraud, who dis- 

 covered the larvae of Pimyla graminellae feeding in a gall on 

 Trificum repens.

Mr David Kobertson, F.L.S., F.G.S., exhibited specimens of 

 entomostraca and foraminifera, taken from mud brought up on 

 the fluke of an anchor, in the Bay of Yokohama, Japan, and which 

 he had received from Mr John Kirsop. A number of the species 

 of ostracoda are new to science, and are of importance as afl'ording 

 confirmation to other inquiries of the day. It is of considerable 

 interest to find along with these specimens a valve of Telllna 

 calcaria (Chemnitz), a highly northern species, and one of the test 

 Arctic shells of our Scottish glacial clays, but which is not now 

 living in our seas. According to Jefl'reys it still survives on tlie 

 Danish coast of the Baltic, northward of Spitzbergen, and in
