Otolithus (Gadus) elegans Koken var. scuplta. (Plate 61, fig. 7a.) 
Dimensions.—5 x З mm. 
Description. —Shape ovate; outer side convex with median ridge and 
umbo, rim serrated ; inner side convex, plain with serrations on edge. 
Suleus straight, traverses otolith but does not cut the front or rear 
dges. 
Occurrence.—Single example from Pukeuri, received from Mr. H. J. 
Finlay. 
Observations.—Described by Koken (3, pl. 4) from the Oligocene of 
Sternberger Gestein. 
Age.— Tertiary (Miocene) : Oamaru series. 
Otolithus (Ophidium) pantanelli Bassoli and Schubert. (Plate 61, fig. 8.) 
Dimensions.—6 x. 4 mm. 
iption.—Shape ovate; outer side convex, smooth with serrations 
on anterior ventral rim ; inner side convex, smooth. Dorsal rim rounded, 
with fold on posterior angle; ventral rim deep with serrations below the 
ostium. Suleus straight; cauda terminates some distance from posterior 
m А 
Occurrence.— Castleclift, l example; Pukeuri, 4 ; Ardgowan, 2; Target 
Gully, 1; Clifden, 1; Waikaia, 5. The Pukeuri specimens were received 
Observations.—This species was described by Bassoli in 1906 (1, p. 43) 
from the Pliocene of Monte Gibio and the Miocene of Pantano, Italy. It 
1 very distinctive in shape and in the formation of the suleus, and appears 
to range from the Upper Pliocene of Castlecliff, North Island, down to 
the Oligocene or Miocene of Waikaia, where it is well represented, per- 
sisting throughout those Tertiary formations of New Zealand furnishing 
the material submitted to me. 
Age.— Tertiary (Pliocene and Miocene): Oamaru and Wanganui series: 
Otolithus (Trachinus) mutabilis Koken. (Plate 61, fig. 9.) 
Dimensions.—4 x 24 mm. 
Description —Shape ovate; outer side concave, inner side convex, 
front pointed; no rostrum or antirostrum. Sulcus straight; cauda in- 
clined slightly upward.

that this example should be referred to the Trachinidae. The sulcus differs — 
slightly from Otolithus (Trachinus) mutabilis described by Koken (2) in 
and t 
south-west France, and in one of these the sulcus is nearer that of exam 
- 
now described. I have therefore referred this example to the species 
described by Koken as Otolithus ( Trachinus ) mutabilis. 
Age.—Tertiary (Miocene): Oamaru series.
