brown, base of joints (from the fourth) pallid. Thorax convex, 

 but depressed near the hind margin ; lateral tubercle small, 

 conical ; colour above bright tawny, with six blackish-brown 

 vittae; sides ashy, with a broader and paler dusky stripe. Scu- 

 tellum pale tawny ochreous. Elytra dilated a little behind the 

 middle, depressed, and thickly punctured (except towards the 

 apex), rusty tawny, with a few short ashy streaks and a number 

 of dark-brown strigse a little behind the middle, the innermost 

 of which runs near the suture to the apex : the basal half of the 

 suture is broadly margined with dusky, and there is a short 

 blackish stripe on each side near the scutellum, and a broad 

 patch of similar hue beneath each shoulder, on the upper edge 

 of which is an ashy streak, which continues in a curved line to 

 the lateral margin, and then to the apex. Body beneath ashy ; 

 sides of breast and abdomen dark brown. Legs reddish ; femora 

 and tibiae each with a blackish ring round the middle. 



I met with the female only of this remarkable species, which 

 differs so much from the other Eudesrni in the shortness of the 

 muzzle. If the male, when discovered, should be found not to 

 possess the swollen third antennal joint, the species will have to 

 be removed from this genus. It was found at Ega.

 Australian Tertiaries. By P. Martin Duncan, M.B. Lond., 

 Sec. Geol. Soc. 



[Plate VIII.] 



The corals about to be described were derived from the same 

 Tertiary beds which yielded the species noticed in the 'Annals' 

 for Sept. 1864*. A new genus is represented by three well- 

 marked species; the well-known genus Sphenotrochusf has two 

 species in the collection; and the genus Antillia J, which attains 

 so great a development in the Nivaje shale of San Domingo, is 

 represented by a very interesting new species. 



List of Species. 



1. Sphenotrochus australis, Woods & Duncan, sp. nov. 

 2. emarciatus, sp. nov. 



* The Rev. J. Woods, who collected those formerly described, classes 

 the various beds of Muddy Creek, Geelong, and the Murray beds as the 

 " Hamilton " Tertiaries. I have to thank him for the specimens now 

 determined and for others which require some further study before their 

 publication.
