THE EGGS AND EMBRYOS OF SCHLEGEL'S GAVIAL 
(TOMISTOMA SCHLEGELI, S. MÜLLER). 
By А. L. BUTLER, F.z.s., M.B.O.U., ETC., 
LATE Curator OF THE SELANGOR MUSEUM. 
QCHLEGEL'S GAVIAL has only been recorded from the Malay 
Pen pem since 1896 (Boulenger, P.Z.S., 1896, p. 628), and so 
little is Fai ©. rel gy that the following note on its eggs and 
young may béo 
On the 28th ^ J m 1899, when I was at Kuala Selangor, Mr. Hale, 
the District Officer, gave me six large crocodile’s eggs for the Museum. 
He 
the same time and brought in for the Government reward of 10 cents 
an п egg. о thaw eleven were destroyed ped = kept for ше. 
ur I found to be addled, the remaining tw taining young croco- 
diles, which, from their abruptly pointed bk. like snouts, I at once 
recognised as young gavials. 
All the eggs were very uniform in size; two of them measured 
4 x 25 inches and 33 x 21 inches 
rom the large size and number of the eggs they were probably 
сорок by a gavial considerably larger than any yet obtained in the 
largest Peninsular Umen at present recorded 
(бош Trai) measured 8 feet 9 inches 
One of the two young gavials extracted from the eggs measured 
65 inches in total length and 3} inches from snout to vent. In estate 
it was dark grey, the tail lighter marked above with 12 transverse 
black bands, interrupted on the dorsal line (5 bands on the body and 
7 on the tail) ; the lower parts were white. 
top of the head had a whitish appearance caused by the brain 
шз through thin and semi-transparent skull, but this eder 
disappeared before the young leave the egg. 
The snout of this embryo specimen was only about twice as long ` 
of 
as its width at the base, or about the same length as the rest 
the head.

It is rather аяна if the inference here drawn is correct. In the case of 
common crocodile the eges are of у very uniform size, quite irrespective of 
the Dump cem of the mother. There are five eggs of the Malayan Gavial in 
the Perak Museum. eir measurements are as
