of Edinburgh, Session 1884-85. 
281 
ments of the stomach, from one to seven inclusive, contained a 
brownish mucus, — the eighth and ninth contained a bile-stained 
fluid, with a number of opaque crystalline lenses and hard white 
calcareous bodies, which looked not unlike the otoliths of Ash. 
The tenth compartment contained several ounces of a bile-stained 
fluid, but no other contents. 
The liver, heart, lungs, pelvic bones and penis, hyoid apparatus, 
and other bones of the skeleton were examined. A dissection was 
made of the extensor and flexor muscles of the flippers, and of the 
vessels and nerves of these limbs. [It is intended to publish a more 
detailed account of the visceral anatomy in the Journal of Anatomy 
and Physiology , October, 1885.] 
6. Preliminary Report on the Cephalopoda collected by 
H.M.S. “ Challenger.” Part II. The Decapoda. By 
William E. Hoyle, M.A. (Oxon.), M.R.C.S. 
It is rather remarkable that the Decapoda should have yielded 
fewer new forms than the Octopoda, although judging by the 
number of genera contained in them, the former is a much more ex- 
tensive group than the latter, and is furthermore represented by a 
larger number in the “ Challenger ” collection, as the following 
synopsis* will show : —
