 Zealand ' Ind. & Colon. Exhib. London, New Zealand Court, Catal.

This form is represented by an example measuring 145 mm. in 

 diameter, with an umbilicus of 12 per cent, and a whorl-thickness 

 of 21 per cent, of the diameter. The terminal portion of the outer 

 whorl belongs to the body-chamber. Whether Dr. Trechmann's 

 example (labelled Streblites) is identical with Hector's type 

 cannot be decided without examination of the original. The latter 

 seems to have a smaller umbilicus, but the type of ornamentation is 

 well, if somewhat diagrammatical^, represented in Hector's figure. 



Bcehm's ' Streblites'' motutaranus 1 has strongly marked primary 

 ribs on the inner half of the sides, reminiscent of Streblites pictus 

 (Quenstedt), and the Uhligites suture-line with a peculiarly 

 undercut external saddle. It shows slightly prorsiradiate costa- 

 tion, but is considerably smaller than the specimen here discussed. 



Uhligites hectori probably belongs to the group of U. Tcraffti 

 (Uhlig & Suess) 2 and U. crassicostatus (Uhlig), 3 well represented 

 in the Spiti Shales. Uhligites nouhuysi (Bcehm) 4 is a smoother 

 though similar type, and more involute forms occur also in the 

 Kimmericlgian of Mexico: for instance 3 Streblites uhligi and 

 Sir. oneocicanopictus Burekhardt. 5
