[417] Mr. Clark (ibid. 62) observed only rough points on the bots of the sheep, but these also have spines or hooks looking towards the anus. Reaum. iv. 556. t. xxxv. f. 11, 13, 15. I also observed them myself in the same grub.

[422] De Geer, vi. 395—. Plate [XXIII]. Fig. 7. Foreleg, a. Hind-legs, bb. Mr. W. S. MacLeay is of opinion that these legs are pedunculated spiracles, (Philos. Mag. N. Series, No. 9. 178.) but it is evident from De Geer's account that the animal uses them as legs, and like legs they are armed with hooks or claws.
