Note 256 — LETTER V.

Linn. Lach. Lapp. ii. 45. In the passage here referred to, Linné speaks of two species of Œstrus, though the mode of expression indicates that he considered them as the same. One was Œ. nasalis from which they freed themselves by snorting, &c., the other Œ. Tarandi which formed the pustules in their backs. In Syst. Nat. 969. 3. he strangely observes under the former species, "Habitat in equorum fauce, per nares intrans!" confounding probably Œ. veterinus of Mr. Clark with the true Œ. nasalis.
