along the east side of the low hills that extend behind Oamaru as far north 

 as the Waitaki Valley. Park (Trans. N.Z. Inst., vol. 37, p. 512) names 

 twenty-eight species, but of these, even allowing for synonyms, only ten 

 occur in our list. 



It is remarkable that neither Hutton nor Park mention Cucullaea, for 

 we found it in considerable numbers, and it is always conspicuous. We 

 found that the following were the most abundant : Lima colorata, Cucullaea 

 alia, Marginella harrisi, Venericardia inaequalis, Malletia ausfralis, and 

 Turritella rosea. 



Target Gully. (Fig. 1.) 



This shell-bed is situated half a mile along a small gully that extends 

 north from Eden Street directly after it crosses the bridge (fig. 2). 

 Hutchinson's Quarry is at the entrance of this gully. The order of 

 succession is — Target Gully shell-bed, Hutchinson's Quarry beds, calcareous 

 tufis. Though no continuous section is exposed, the field relations are

clear, and we have no doubt that the three beds are conformable. It 

 appears that the Target Gully beds have escaped notice hitherto, for we 

 can find no reference to them by McKay or Hutton, and Park states that 

 there is nothing in the neighbourhood of the Hutchinson's Quarry beds to 

 indicate their age. 



The bed from which our collection has been made is about half-way 

 up the east side of the gully, about 50 ft. above sea-level. One hundred 

 yards distant the calcareous tuffs crop out, about 25 ft. lower. The bed 

 is mainly composed of drifted shells, of which many are broken. They 

 are contained in grey sand, weathering orange from the oxidation of 

 the iron contained in the glauconite, which occurs in the sand in some 

 quantity. The shell-bed is 4 ft. thick, and is 8 ft. long in the exposed 

 portion. From this limited exposure sixty-nine species of Mollusca have 

 been identified at present. There are, in addition, several sm ill species 

 that we have not been able to identify, and we hope to give a more com- 

 plete list next year.
