Victorian Fossils, Part XVII I. 1(51 



Fam. Proetidae, Corda. 

 Genus Proetus, Sbeininger. 



I 'roetus eurycejia, McCoy sp. (Plate XIV., Fig. 4). 



Forbesia euryceps, McCoy, 1870. Prod. Pal. Vict., Dec. III. p. 

 IT. pi. XXII., figs, lo. 10a. 



Observations. — Since McCoy's description, several specimens 

 have come under my notice. 



A finely preserved example from Ruddock's quarry near Lilydale, 

 in the possession of Mr. J. S. Green, shows the surface of the cara- 

 pace to be minutely granulated. This serves to clear up any 

 doubt regarding the surface ornament; for McCoy remarked, in 

 his description of the species 1 : " The surface is indistinctly pre- 

 served, but 1 think it is minutely granular." 



A small, but nearly perfect example of the same species was 

 found by Mr. Annear, near Lilydale, and is now in the Museum 

 collection. It measures only 7 nun. in length. In this specimen 

 the free cheeks and genal spines are distinctly granulate. 



In a series of Silurian fossils from Loyola submitted for descrip- 

 tion by Mr. Ceo. Sweet, F.G.S., there is another example of the 

 above species. This has since been presented to the collection. The 

 cephalon is fairly well preserved, and the rest of the carapace can be 

 generally made out, showing the rapidly tapering axis. The 

 granulation above referred to is well shown, especially on the 

 glabella and anterior rings of the thorax. This example is also 

 small, measuring only 7.5 mm. in length. 



Horizon and Occurrence. — Holotype (described by McCoy) in 

 Nat. Mus. Silurian. Broadhurst's Creek. E. of Kilmore. Bbl8. 

 Ceo]. Surv. Vict. 2 . Also specimens from the Silurian (Yeringian) 

 of Ruddock's quarry, near Lilydale, coll. by Messrs. J. S. Green 

 and R. H. Annear; and from Loyola, near Mansfield, coll. by Mr. 

 Geo. Sweet. F.G.S.

2 In my paper " on the Palaeontology of the Silurian of Victoria," (Rep. Austr. Assoc. Adv. 

 Sci., Melbourne Meeting-, 1913, vol. xiv.), p. 208 and lists, this locality was included in the Mel- 

 bournian Series. Further considerations of the faunal assemblage of these and the allied beds at. 

 Wandong', containing Dalmanites meridianus, lead me to place them low down in the Yeringian, 

 or probably representing a passage series.
