it is not actually found with Monotis, it is associated with fossils that are 

 also common to the lower triassic formation. It is near to B. elongatus of 

 the lias of Britain.

According to Dr. Waagen this is very nearly the same as B. kuntkotensis 

 of the lower Jurassic formations of Kutch,* and, according to Professor 

 Taite, is hardly distinguishable from B. sulcatus of the lower oolite of Great 

 Britain.! 



Occurs in dark-coloured marly sandstones of the Putataka series, 

 Waikato South Head, and also in similar strata in the Hokauui Eange, 

 Southland. In the latter case it occurs in the upper part of the Putataka 

 series, associated with Trigonia costata and other middle Jurassic fossils. 



3. Belemnites catlinensis, sp. nov. 



PI. XXII., fig. 3, a, b. 



Guard slender, sub-hastate from being constricted below the alveolus, 

 and widest at the distal third of its length, where the diameter is one- 

 twelfth of the total length and half the length of the alveolus. Phragma- 

 cone acute, forming an angle of 18°, with about 16 septa, eccentric, the 

 apex being nearer to the ventral margin. A wide groove extends along the 

 ventral surface from over the alveolus, but disappears short of the apex. 

 In section the guard is slightly compressed. Total length of largest 

 specimen, six inches. 



In dark-coloured argillaceous sandstones, south of Catlin Eiver, Otago, 

 and in the Hokanui Eange, where it is associated with Ammonites novcB- 

 zealanclice. 



This species is very near to B. fusi/ormis of the lower oolite of Britain, 

 and to B. gerardi of India;! but if faint lateral vascular markings are to 

 be considered as true furrows, as in that species, both this species and B. 

 aucklandicus must be classed with the group Hastati, in which case no 

 representative of the Canaliculati has yet been found in New Zealand. 



B. — Hastati.
