paper " Zur Kenntnis des javanischen Flugfrosches," in the 

 Biologischen Centralblatt, Bd. xxix., Nov. and Dec. 1909, in 

 wliich he describes the nesting-habits of Polyjyedates reimoardfdi. 

 These present some interesting points of comparison with those of 

 P. sauvagii. The general economy of the nests is the same, but 

 in Polypedates the protection for the eggs and the source of fluid 

 for the developing embryos are supplied by a stiff foamy substance 

 instead of by empty egg-capsules (though Siedlecki states that 

 empty egg-cases ai-e often laid). This substance is distinct from 

 the oviducal egg-membranes, which are embedded in the frothy 

 mass, the whole being suspended in leaves as in Phyllomedusa. 

 The majority of the eggs are in the centre of the mass, the outer 

 layers containing comparatively few eggs. It is the foamy substance 

 which appears to give up its water to the developing embryos, 

 like the empty egg-cases in P. sauvagii. After hatching, the 

 tadpoles remain for twenty-four hours or more in the fluid thus 

 obtained, which now lies in the interior of the hollow nest formed 

 by the dried outer layers of the fi-othy mass. The tadpoles are 

 finally freed by the giving way of the wall of the nest under the 

 softening influence of the fluid inside, or of rain, or of both. —

(Plates LXXXV. & LXXXYI.f) 



The collection was made during the spring of 1907, and 

 entrusted to us for identification and description by Professor 

 Bourne. It contains one species of Turbinolidte, one species of 

 Flabellidae, two species of Fungiidse, and ten species of Eupsam- 

 miidae including one new species of Balanojyhyllia. 



We wish to take this opportunity of thanking Dr. Bourne for 

 much help and advice. Professor Herdman for the loan of two 

 species of Bcdanophyllia, and Professor Jeffrey Bell for permission 

 to examine the Eupsammiidte in the National Collection ; also 

 Dr. E. H. J. Schuster and Mr. Robinson for the photographs on
