Cythere sciNTiLLULATA, G. S. Brady. (Plate VIII., Fig. 26). 



Cythere scintillulata, G. S. Brady, 1880, Rep. Chall. Zool., 

 vol. i., pt. iii., p. 62, pi. xiv., figs. -ia-d. 



Observations. — This species is represented by one typical speci- 

 men in the bores, at a level showing a mixed Kalimnan (Lower 

 Pliocene) and Janjukian (Miocene) fauna. This is its first occur- 

 rence in the fossil state. 



C. scintillulata was dredged in the Straits of Magellan by the 

 ■" Challenger," at 55 fathoms. 



Occurrence. — Bore 5, 189-190 (Janjukian). 



Cythere scutigera, G. S. Brady. (Plate VIII., Fig. 27). 



Cythere scutigera, G. S. Brady, 1868, Les Fonds de la Mer, 

 vol. i., p. 70, pi. viii., figs. 15, 16. Idem, 1880, Rep. 

 Chall. Zool., vol. i., pt. iii., p. 109, pi. xxii., figs. Sa-/. 



Observations. — ^^This species, as represented in the Mallee Bores, 

 ishows the general specific characters of the recent species, but is less 

 •distinct in the sharper features of the carapace. 



Brady has recorded this species from Amboyna, Java and Papua. 



Occurrence. — Bore 11, 442-444 feet (Janjukian). 



Cythere wyville-thomsoni, G. S. Brady. (Plate VIII,, Fig. 28). 



Cythere wi/viUe-thomsoni. G. S. Brady, 1880, Rep. Chall. 

 Zool., vol. i., pt. iii., p. 82, pi. xx., figs. 4«-/. Egger, 

 1901, Abhandl. d. k. bayer. Akad. Wiss.. vol. xxi. abth. 

 ii., p. 444, pi. vi., figs. 13-14. 



Observations. — A single specimen of this form, typical in neaily 

 ;all its characters with the recent form, but not so spinous at the 

 ■extremities, and with more parallel sides, occurs in the Janjukian 

 •(Miocene) of the Mallee bores. 



The " Challenger " obtained it from Heard Island and Kerguelen 

 Island in the Southern Ocean, and in Torres Strait. Egger's 

 ■" Gazelle " specimens came from the west coast of Africa. 



Occurrence. — Bore 10, .'UO-320 feet (Kalimnan or Janjukian).
