Phillip-na eJom/afa Mitchell. 

 Fig. 14. — Portion of a head-shield, thorax, and tail. The markings on the 

 basal glabellar lobes are accidental. The normal glabellar frontal 

 limli and anterior courses of the facial sutures are shown. (Coll. 

 Geological and Mining Museum, Dept. of Mines, Sydney. No.ri498; 

 Pal. Mem. Pt..!. No.2, PI. xxi., fig.2). 



PJullipsia superlKi Mitchell. 

 Fig. lo.^Cephalon minus the right free cheek. (Coll. (ieologieal and 

 Mining Museum, Dept. of Mines, Sydnej-. No.'24). 

 Phillipsia iraterhoHsei Mitchell. 

 Figs. 16, 17, 18. — The first and second of these are from an intaglio, and 

 the other is from a squeeze from it. With the aid of a lens, the 

 features can be made out. (Coll. Geological and Mining Museum, 

 Dept. of Mines. Sydney. Nos. 28 and 30). 



Plate xlix. 

 PhiUipsia iroodnrirdi Eth.fil. 



Figs l-fi. — Pygidia, all assumed to belong to this species. All show prac- 

 ticallj' the same features. Figs. 3 and 4 are more strongly gran- 

 ulated than the others; but this difference probablj^ arises from 

 degrees of weathering. Fig. 5 was figured by Mr. Etheridge {op. cit. 

 PI. viii., fig. 6) as the normal tail of his P. dubia. (Coll. (geological 

 Museum, Dept. of Mines, Brisbane. Nos. F 985, F 1024, F 995, 

 F 1026, F 968, F 993). 



Figs. 7-8. — Photos of a fragmentary cephalon, about which I am doubtful 

 that it is rightly placed here. It is one of Mr. Etheridge's types 

 (Geol. and Pal. Queensland and New Guinea, PI. vii., fig. 13). (Coll. 

 (Geological Museum, Dept. of Mines, Brisbane. No. 967). 

 Phi//ipsia roekhamp)toHensi-s Mitchell. 



Figs.9-10. — Two prints of a nearly complete specimen. Fig. 10 has some 

 of its features intensified. This specimen was figured by Mr. 

 Etheridge, Junr., and determined to belong to his P. duhia {op. cit., 

 PL xliv,, fig, 4). This figure very indifterently represents the 

 original, as will be seen by comparing it with the present photos, 

 which show its chief characteristic features clearly. (Coll. Queens- 

 land Museum, No. 716). 



Phillipsia morgane.nsis Mitchell. 



Figs. 11-12. — Fig. 11 represents portions of a cephalon, thorax, pygidium, 

 and a hypostome. Fig. 12 is a rough sketch of part of a cephalon. 

 (Coll. Geological Museum, Dept. of Mines, Brisbane, No.F 1000). 

 Phillipsia woodwardi Eth.fil. 



Figs. 13-14. — Photos of the type-specimen. Fig. 14 has the outline traced 

 in, (Coll, Geological Museum, Dept. of Mines, Brisbane. No,966).
