him in due course. For the moment he asked the meeting to pass this 

 vote of thanks to Mr. Parsons for the excellent services he had per- 

 formed for the old Society at a time when it most required them. 

 Carried by acclamation. 



Mr. Scour field said he had brought that evening some specimens of 

 the ordinary or parthenogenetic female, the ephippial female, and the 

 •male of the Entomostracon Simocephalus exspinosus. In the ephippal 

 female there was a modification of the back of the shell, known as the 

 ephippium, intended for the reception of the resting Qg^. The ephippium 

 when thrown off could be dried up or frozen, but its contained Qgg 

 would hatch out when the conditions became favourable again. Males 

 and ephippial females occurred only at certain seasons of the year, and 

 he had records of the occurrence of these forms in the Epping Forest 

 district from which it appeared that they were to be found mainly in 

 June and October, or round about those months. It was, however, a 

 very common occurrence amongst the Cladocera, the group to which the 

 specimens of course belonged, that the sexually mature individuals 

 should appear only at certain seasons of the year. The male, it might 

 be mentioned, did not differ very much from the young female, and 

 might therefore be very easily overlooked. 



Mr. Earland then exhibited lantern-slides illustrating some of the 

 species recorded by Mr. Henry Sidebottom in his " Report on the Recent 

 Foraminifera Dredged off the East Coast of Australia, H.M.S. ' Dart,' 

 Station 19 (14th of May, 1895), lat. 29° 22' S., long. 153° 57' E., 

 465 fathoms." 



The President said he was sure it would be the wish of Fellows to 

 record a hearty vote of thanks to Mr. Sidebottom for his communication, 

 which, in due course, would appear iu the Society's Journal, and also 

 thanks to Mr. Earland for showing and explaining the slides. 



Carried by acclamation. 



Mr. F. Martin Duncan then communicated a paper, " On Mounting 

 and Preserving Marine Biological Specimens," but owing to the lateness 

 of the hour it was agreed to ask the author to exhibit the slides illustrat- 

 ing the paper at the next Meeting of the Society. 



The President proposed a hearty vote of thanks to Mr. Martin 

 Duncan for the paper, and also that 'the best thanks of the Society be 

 given to Mr. Angus for the loan of the microscopes used for the" ex- 

 hibitions o^ the evening, both of which were carried unanimously. 



The next Meeting was announced for November 21, and the next 

 Meeting of the Biological Section for Wednesday, November 7.
