continuous curves independent of the latter, and not con- 
uent as in Olenellus. The fixed cheeks are very narrow, 
whilst the facial sutures are much pinched-in at the anterior 
ends of the palpebral lobes, giving to the antero-central por- 
tion of the vadunt shield a very characteristic ‘‘halbert’’- 
shaped appeara 
To this genus 1 now refer Olenellus ( * ) lagga? Eth. fil., 
and Foord, from Kimberley. A denda tpe A. H. Foord’s 
figure (40) will at once reveal the v close r d exist- 
ing between O.(?) forresti and Redlich’s H beso noetlingi, 
the type species of Redlichia, and following Mr. Walcott's 
suggestion ^U T now transfer it to that genus.

Obs.—Mr. G. F. Matthew suggested the reference of this 
Trilobite to his genus Protolenus on account of its continuous 
eye lobes. He remarked that these continuous eye lobes ''are 
close to the glabella, leaving a very narrow fixed cheek. The 
eye lobes and the middle piece of this head-shield are well 
PDA) and give no reason for supposing that the outer cheek 
as fixed, without which the reference to Olenellus is in- 
aalihi 
servo; opposition to Mr. Matthew's suggestion I would 
o 
. The coe appearance of the glabella, fixed cheeks, 
and ux lobes respectively in Voici 1) forresti is n dif- 
ferent from that of Matthew’s type, Protolenus elegan 
2. ds labella in Protolenus bears three pairs of p 
furrows, but in x Australian "Trilobite these furrows are 
Loiad, and said to be four in number. 
3. In Matthew’s type a pygidial api is unknown, but 
he informs us that such an appendage exists in a Sardinian 
Species, and is like that of yta 1 or Olenus)." Mr. 
Foord remarked :—‘‘From the same locality as the head just 
described there is a short spine (fig. 2a), probably MER 
to the present species; if so, it would be t the telson.” (42 
however, suggest it may be one ‘of the genal spines id 
therefore quite in keeping with the structure of Redlichia.
