2. Name op the Golden-crowded Thrush. — Originally and 
usually written aurocapillus, which should give way to auricapillus. 
The word means simply “gold-hair,” i. e., “golden- haired.” The 
point is here : that the ablative of durum., “ gold,” which is auro, is 
only to be used when the word with which it is compounded is an 
adjective or participial ; otherwise auri is the correct form. If we 
were to employ the participial adjective capillatus, it would be correct 
to say aurocapil/atus, i. e., literally and correctly, “haired with 
gold,” auro being the ablativus instrumenti, that with or by means 
of which the bird is “ haired.” So we say rightly aurocristatus, 
aurostriatus, auropunctatus, crested, streaked, or speckled ivith gold, 
(color understood), but auriceps, auricollis, Auriparus, etc. So also, 
if we were to compound with the adjective aureus, “ golden,” we 
should say, e. g., awreicmda, not aureocaudatus. Either aureicapillus 
or auricapillus is correct, but aurocapillus is not.

reason, common sense certainly tells us to spell correctly if we can. If we are 
always to preserve the original forms of names, we must, for example, say Scopo- 
lax instead of Scolopax — it so stands in Linn. Syst. Nat. i, 1766, p. 242.
