262 ON THE ANATOMY OF CERTAIN PARROTS. 
2. Deroptyus accipitrinus. A Brazilian specimen of this rather 
peculiar genus from the Society’s collection has the two carotids 
arranged as in Dasyptilus, the left being superficial. The furcula is 
of fair size, the orbital ring incomplete, the oil-gland well tufted, the 
ambiens muscle absent. 
3. Polyteles barrabandi possesses two carotids, normally situated— 
in other words, side by side in the hypapophysial canal. The furcula 
issmalland slender. The oil-gland is decidedly large, and well tufted. 
There is no ambiens muscle. The intestines measured 40 inches. 
4. Chalcopsitta scintillata has the two carotids normally situated, 
a small furcula,a small tuft to the large oil-gland, and no ambiens 
muscle. The intestines measured 37 inches. 
5. Coriphilus fringillaceus has the two carotids normal, the furcula 
small and slender, no ambiens muscle, and a well-tufted oil-gland. 
This specimen was kindly given me by Canon Tristram, carbolized 
and dry. 
Of genera which have already passed through my hands I have 
had the following additional species :— 
Ara militaris. Licmetis tenutrostris. 
Cacatua moluccensis. Lorius domicella. 
philippinarum. Paocephalus meyert. 
Hclectus grandis. Tanygnathus albirostris. 
Eos reticulata. 
They all agree with those species previously dissected, except 
Licmetis tenwirostris, which has only one carotid, the left, whereas 
L. pastinator has two. It will be interesting to verify this difference 
between the South-Australian species and its more western ally ; for 
the uncertainty of the disposition of these vessels in the Cacatuine is 
rendered more striking if it is correct. 
In the specimen dissected, of Cacatua philippinarum, a gall-bladder 
was present. Thisis the only case in which I have seen this viscus in 
any Parrot. 
Formulating the varying characters of the above newly dissected 
genera upon the principle adopted in my earlier paper and there ex- 
plained, the formule run thus :-— 
(1) Dasyptilus 2.—.+.+. (4) Chalcopsitta 2.—.+.+. 
(2) Deroptyus 2.—.+.+. (5) Coriphilus 2.—.+.+. 
(3) Polyteles 2.—.+.+. 
Such being the case, Dasyptilus and Deroptyus fall into my sub- 
family Pyrrhurine, whilst the other three must be placed with the 
Palwornithine. It is interesting to notice that Deroptyus agrees with 
Pyrrhura, and not with Conurus.
