424 PROCEEDINGS OF THE SOCIETY. 



completed, will be of no use except to the Curator and the few Fellows 

 who frequent the Society's rooms. 



We take it that the Society will not in the present financial period 

 be prepared to spend money ou either of these objects, and, indeed, 

 at the present time the gaps in the collection are too obvious to make a 

 printed catalogue desirable. We think, however, that this would be 

 a very suitable time to fill in the gaps, so that the catalogue when 

 ready for printing may worthily represent the collection of the Royal 

 Microscopical Society. There must be numerous Fellows, and other 

 microscopists working at special groups, who would respond cheerfully to 

 an invitation to give some of their best work a home in the Society's 

 cabinet, and with this end in view we conclude our Report with an 

 Appendix showing how the groups are now represented, and indicating 

 the gaps which it is desired to fill. A Fapt anti

Appendix to the Report. 

 Animal Kinr/dom. 



The sul)-kingdom Protozoa is very sparingly represented in the 

 cabinet apart from Foraminifera, of which there are over 100 named 

 species and some eighty spread-slides. The Infusoria, the Mastigophora, 

 and the Lobosa are each represented by a single slide, but the Sporozoa 

 and Heliozoa are entirely unrepresented. There are about 20 Radiolaria, 

 but nearly all spread- slides. 



Sponges are represented by some 70 preparations, a poor selection 

 except so far as fresh-water sponges are concerned. Many of the 

 specimens require naming or re-naming. 



CodenUrata are very poorly represented, only about a dozen Hydroids 

 and as many Gorgonids. 



Worms. — A very poor series, about 50 slides, but interesting histori- 

 cally as they include mounts by Cobbold, Rosseter, and Bastian. 



Rotifera. — Less than a dozen mounts, in good condition. 



Crustacea. — Very poorly represented by about 50 slides, 29 or more 

 of which are hard sections. There are only a few mounts of Cladocera 

 and Ostracoda. 



Myriapoda. — Two slides only. 



Acarina. — There is a fine set of over 100 OribatidaB, given by 

 Mr. Michael, but very few of other groups. 



Pseudoscorpions. — One only. 



Ticks. — About a dozen. 



Spiders. — About 15, some good. 



Pycnogonida. — Two mounts only. 



Insects. — A considerable number of slides, but not many high-class 

 preparations. 



Thysamira and Collemhola. — Over 30 mounts of Podura scales, 

 which Mr. Barnard has undertaken to examine.
