date of reading at the Society. My paper in Trans. Zool. Soc. was 
read Nov. 19th so that I cannot legally claim priority; but I hold in 
my hand a receipt from the Secretary of Zoological Society acknow- 
ledging my communication, dated June 6th, 1895. Moreover early 
this year I published, by permission of the Secretary, an abstract of 
my paper in the Proc. Birm. Nat. Hist. and Phil. Soc. My conclusions 
there stated were as follows: — 
1) Suprarenals are almost certainly present in all 
Elasmobranchii, Holocephala, Ganoidei, and Teleostei, 
and very probably in Dipnoialsot). 
2) In Elasmobranchs the interrenal body is totally 
distinct and separate from the segmental bodies, and 
there is no kind of connection between them. 
3) There is no “third kind of body” in relation to the 
kidneys of Scyllium, as BALFOUR surmised there might be. 
4) The yellow bodies scattered in the Sturgeon’s kidney are the 
true suprarenals of Ganoids, and correspond to the interrenal of Elasmo- 
branchs and the suprarenals of Teleosts. 
5) In the Teleostei the suprarenals are usually two 
in number, placed on either the dorsal or ventral sur- 
face of the kidney, usually near its posterior extre- 
mity. 
6) In Elasmobranchs the interrenal body consists of 
definite alveoli, containing cells with large nuclei and 
curious structures somewhat resembling the “demi- 
lunes” of mucous glands. 
The alveoli are seen in some parts of the gland to be arranged 
in a radiating manner round veins or venous sinuses. The general 
appearance is very like that of the cortex of a Mammalian supra- 
renal, and it is almost identical with the cortical cell-columns of Am- 
phibians and Reptiles. 
7) The segmentally-arranged bodies in the Elasmobranchs have 
no cortex and medulla (though so described by BALFOUR), no definite 
alveoli, and, for the most part, no definite cell-outlines ?). 
This curious indefiniteness marks off the paired suprarenals of 
the Cartilaginous Fishes from all the other structures we shall have 
1) Since the above has been in type I have seen Perrit’s work 
(These, Paris 1896). This author claims to have found the suprarenals in 
Protopterus annectens. 
2) Since writing the above I have succeeded in making out cell- 
outlines by carefully examining with oblique light.
