The specimen sent by Commander Cookson exhibits a previously 
undescribed plumage of these insular Mimi; it is most probably a 
young individual. 
2. DENDR@CA AUREOLA. 
Dendreca aureola (Gould) ; Salvin, ¢. ¢. p. 473. 
Three specimens from Charles Island, representing an old female, 
a young male, and a young female. The young male bird is in an 
interesting plumage, having the under surface yellow, the throat 
white with a few yellow feathers intermixed, while on the breast the 
reddish streaks are just beginning to appear. 
3. GEOSPIZA FULIGINOSA. 
Geospiza fuliginosa (Gould) ; Salvin, ¢. c. p. 482. 
Three young specimens from Albemarle Island, whence no Geo- 
spiza has as yet been recorded. Two are nestlings, the smallest 
being uniform creamy buff below, and having very broad rufous 
edgings to the wing-coverts and quills. The specimen appears to 
be full-grown, and measures as follows—total length 3:9 inches, 
wing 2°4, tail 1°7, tarsus 0°8. The Albemarle species would ap- 
pear from these dimensions to be G. fuliginosa, as they are too big 
for G. parvula, and there is also a specimen of a young G. fuliginosa 
from Indefatigable Island (adel) in the British Museum, with 
the plumage of which the Albemarle skin agrees very well indeed. 
4. PyROCEPHALUS NANUS. 
Pyrocephalus nanus (Gould); Salvin, ¢. e. p. 492. 
No specimens of these Ruby- crowned Flycatchers have been before 
recorded from Charles Island, though Dr. Habel says that the spe- 
cies was found on all the islands visited by him. Commander 
Cookson has sent five specimens, two of which, now that they are 
made into skins, are yellowish where the adults are red ; this is pro- 
bably owing to the action of the spirit upon the plumage, and does 
not point to the specific distinctness of the Charles-Island bird. A 
young male in changing plumage shows a decided shade of red ap- 
pearing on the under surface. 
II. Reprites. By Avsert GUNTHER. 
The two species of Tortoises (Testudo microphyes from Albemarle, 
and Testudo abingdonii from Abingdon Island) will be fully described 
and figured in the author’s forthcoming work on Gigantic Land 
Tortoises. 
Only five species of Lizards are known from the archipelago, of 
all of which specimens were obtained by Commander Cookson. 
For a full description and figures I refer to the excellent paper re- 
cently published by Dr. Steindachner (“ Die Schlangen und Kidechsen 
der Galapagos Inseln,”’ Festschrift der zool.-bot. Ges. Wien, 1876, 
4to). ‘Their distribution in the archipelago is as follows :—
