No. 98. A shell of 8 whorls, having the general shap& 

 of 0. australis Duel., and an average specimen measuring 

 23 cm. X 10 cm. The mouth is 17 cm. X 5 cm., but 

 vmlike australis its posterior canal is closer to the body- 

 whorl. The ground colour is tawny yellow, marked by 

 faint chestaut-coloured spots on the upper half of the body- 

 whorl ; these increase in size and depth of colour, and form 

 zigzag streaks below. 



No. 100. Very closely resembles 0. ispidula L., of which it 

 may be a variety. It differs in size, being usually smaller, 

 and in the shape of the mouth. In ispidula the space 

 between the two lips widens gradually from above down 

 ward. In duclosi for two-thirds of the length the lips are 

 nearly parallel. Then the inner lip slopes rapidly. The 

 ground colour of the shell is lighter, and the striations on 

 the columella more numerous. 



The numerals after the species refer to the following localities : — 

 1 Samarai, 2 Gurya Beach, 3 Rabaul, 4 Port Moresby.
