XXIV. Note to a paper on the blood-vessels of Mustelus antarcticus (‘Phil. Trans.,’ 1886)
My attention has been called by a perusal of Professor Milnes Marshall and Mr. C. H. Hurst’s ‘Practical Zoology’ (London, 1887), to an omission in my description of the venous system.

| Summary: | My attention has been called by a perusal of Professor Milnes Marshall and Mr. C. H. Hurst’s ‘Practical Zoology’ (London, 1887), to an omission in my description of the venous system. These authors describe and figure, in Scyllium canicula (pp. 218 and 224) a transverse anastomosis, the inter-orbital sinus , connecting the right and left orbital sinuses, and running in the floor of the skull immediately caudad of the pituitary fossa. I find that this anastomotic trunk is present in Mustelus antarcticus , in which species, however, it hardly deserves the name of sinus being only 1 mm. in diameter in a dog-fish 1 metre long. |
