312 NOTES AND EXHIBITS. 



black, are not by any means, well defined, as they get gradually 

 blended into the brown. The teeth weie of a beautiful clear 

 pinkish red, excepting the tips of the central cusps of the front 

 teeth and the longitudinal ridge of the back teeth which were 

 colourless and pearly. The stomach and bowels were well filled 

 with small fragments of Echini which had been evidently 

 swallowed in numbers, spines and all. The ovaries were full of 

 ova in different stages of development, the largest over 1 inch in 

 diameter, and of a greenish colour; the smaller ones mostly yellow. 

 There was no appearance of anything like the formation of the egg- 

 case, nor did the oviduct appear to have ever been occupied. The 

 animal was altogether thoroughly healthy, there were no Entozoa 

 nor indeed Parasites of any kind, except two specimens of a leech 

 fastened on the palate. The dorsal spines were very strong and 

 flattened above, presenting the appearance of having been much 

 worn down. From this circumstance, coupled with the nature of 

 their food, it may be inferred that the animal is in the habit of 

 forcing itself under rocks and large stones. 



Mr. Brazier exhibited a specimen of Centrostephanus Rodgersii. 



Dr. Cox exhibited several specimens of " Vegetable Caterpillars" 

 found by Mr. Selkirk at the Kurrajong.
