well as many unliatclied eggs, was formed of a wliite crystal- 

 line web, whicli scintillated when the light was placed near 

 it, producing a strikingly beautiful effect. The nest was 

 tightly surrounded by the legs of the female. As yet no 

 insects have been found on which the Theridion troglodytes 

 must subsist, but no doubt further and more careful exami- 

 nation will lead to the discovery of many. The cave con- 

 sists of several chambers, in the innermost of which, where 

 the Arachnidse were collected, is a large deposit of Mamma- 

 lian remains, some of which lie on the projecting shelves of 

 rock, to which they are agglutinated by thick stalactitic in- 

 crustation ; still larger quantities are found in the crevices of 

 the rock, whilst the earthy and stalagmitic floor yields an 

 abundance of the following species, which have been care- 

 fully compared with recent specimens : — 



Halmaturus Bennettii (brush kangaroo) 



Halmaturus Billardieri (wallaby) 



Hypsiprymnus Apicalis Potorous Murinus (kangaroo rat) 



Bettongia Cuniculus (forester kangaroo rat) 



Phascolomys (wombat) 



Phalangista Vulpina (black or grey opossum) 



Phalangista Cookii (ring-tailed opossum) 



Mus Pachyrus (recently obtained from Long's Plains) 



Mus Castaneus. 



No traces of Carnivorous Marsupialia have been found, 

 but from the enormous number of bones here collected, and 

 from the broken condition of the larger number, it is more 

 than probable that these caves were the resort of flesh- 

 eating Mammals. As the floor of the Bone Cave is about 

 30ft. below the level of the present entrance, and is only 

 reached by two well-like descents of from 14ft. to 16ft. 

 each, connected by low passages, it is almost certain that an 

 entrance must have existed on the othev side of the range. 

 The bones, though not fossilized, for the most part bear 

 evidence of considerable age. In a future paper we hope, 

 after careful examination of the cave, to give fuller parti- 

 culars of this most interesting discovery, as well as a larger 

 list of the contained organisms. Wc are informed that the 

 stalactites are truly magnificent, surpassing in beauty those 

 of the well known and justly famed Chudleigh caves.
