sense understood by Goldfuss, before its subdivision by Ed- 

 wards and Haime. 



In the fifth example, previously referred to as probably 

 identical with the other form, the septal spines are well deve- 

 loped. 



Locality and Horizon. Broken River, a tributary of the 

 Burdekin River, North Queensland. Specimens obtained in 

 situ and in partially rounded blocks. Devonian Limestone.

Genus Alveolites, Lamarck, 1801. 



(Systeme des Anim. sans Verteb. p. 375.) 



Obs. We have before endeavoured to point out * the 

 chaotic condition in which the genus Alveolites at present 

 rests. The conclusion at which we arrived, after a very care- 

 ful examination of a large series of corals referable to the 

 Alveolites- Choztetes section of the Tabulata, was : — " Not only 

 does it appear to be evident that the name Alveolites covers a 

 number of forms which are not always united by relations of 

 genuine affinity, but even those forms which may be regarded 

 as types of Alveolites are only separable from certain allied 

 groups by characters difficult to define or discover, and some- 

 times of dubious value and uncertain interpretation." Since 

 these remarks were made, Alveolites has been the subject of 

 further research by one of us ; and in a forthcoming work f it 

 will be shown that this name must be restricted to a small 

 group of species, while many forms which have been indis- 

 criminately assigned to it will have to be distributed amongst 

 other genera. 



We have before us two corals from Queensland, which we 

 have not been able to submit to as complete an examination 

 as we should like. One of them is a ramose form of Alveo- 

 lites, accepting that genus as formerly understood, with affini- 

 ties to Pachypora ; the other is an expanded or lobate species 

 of so-called Alveolites. 



Under this name there have been described from the Palaeo- 

 zoic rocks of Australia the following species : — The Upper 

 Silurian series of Burrow ang has yielded to the researches of 

 Prof, de Koninck J Alveolites repens, Fougt, and A. rapa, 

 De Kon. The Lower Devonian rocks of the same colony 

 have yielded Alveolites subaqualis, Echv. & H., and A. ob-
