t In the present case the specific name of Mr. Gray has been adopted (contrary 
to the rule generally adhered to in this Catalogue) in preference to that of Thun- 
berg, which was founded on an erroneous opinion of the substance with which the 
nest is constructed. 
X To Professor Thunberg belongs the credit of having given that specific rank and 
character to the bird which in the Indian Archipelago constructs the edible nests, 
the Hirundo fuciphaga, Thunb., or Collocalia nidifica, of Gray ; by which it is 
clearly distinguished from the Hirundo esculenta of Linnaeus. The following 
extract from the Transactions of the Stockholm Academy " explains his deter- 
mination. 
" In my ' Travels,' vol. III. p. 319, and vol. IV. p. 164, I briefly mentioned 
the swallow which builds this jelly-like nest in the Tjirraton mountain, in peculiar 
caves, on the island of Java, which I took for Linnseus's JI. escidenta, but which I 
afterwards found, on closer examination, to be an unknown species quite different 
from the esculenta; and since I have not found the same named or described by any 
Ornithologist, I have thought it worthy of being determined by characters, and 
described and still more figured, and thereby become fully known to Ornitho- 
logists. This species, c&Wed fuciphaga, builds its nests like esculenta, in fissures and 
clefts of rocks ; and they form an excellent (both precious and remunerative) mer- 
chandise. Both birds are, at first sight, very like each other, so as to be easily 
confounded. 
"Hirundo escidenta Linn. (Syst. Nat. I. p. 191) is that which Brisson has 
figured (vol. II. t. 46, f. 2, a.) ; but that which Rumphius has had drawn in the 
Herb. Amb. vol. VL t. 75, f. 3, 4, is my fuciphaga. It seems that Rumphius 
had seen and confounded the two species ; that the elder Rumphius in his descrip- 
tion meant H. escidenta, and his son, who drew the figure, had H. fuciphaga for 
his pattern. The following is the description : — 
" ' H. fuciphaga : siipra atra, suhtus dnerea, tota immaculata.

ton ; et alibi in insulis Moluccanis. Coi'pus supra atrum, immaculatum, vix nitens ;
