On new Scarabacidse in the British Museum. 53 



]\rr. Illricli, by givino- figures of so many sections and 

 pointing out fresh and important characters, has done work 

 wliich will lead to a juster appreciation of the position of 

 Palaeozoic Bryozoa. I would urge the importance of a 

 thorough comparison of Palaeozoic with Cretaceous genera, 

 for the number of known Cretaceous genera is very large, and 

 with these and the present fauna comparison can be made, 

 thus giving the best stepping-stone between the rich Carbon- 

 iferous fauna and the recent. 



I would like to ask why Strehhtrypa Nicklesi, Ulricli, 

 pi. Ixxi. fig. 9, should be separated from Fetalopora^, and there 

 are other genera which do not seem altogether new. Should 

 not Worthenopo7'a be Micropora? 



In conclusion, in the Cretaceous MelicertitidaB the charac- 

 ters are in the main Chilostomatous united with some that 

 are Cyclostomatous, and also in a veiy large section of 

 Palaeozoic fossils there are important structures similar to 

 those in recent Chilostomata.

 LiTOCOPRlS, gen. nov. 



I propose this name for a certain number of small species 

 of Copris which differ from the ordinary forms in being 

 more regularly oval ; the clypeus is broadly and not deeply
