Mtxine capensis was recently described by me from a single 

 specimen from the Cape of Good Hope, taken at a depth of 

 110 fathoms (« Annals/ (8) xi. 1913, p. 398). The dentition 

 could not be described, and it was not certain that the presence 

 of seven pairs of branchial pouches was normal and charac- 

 teristic of the species. Dr. L. Peringuez, Director of the 

 South African Museum, has very kindly sent me two examples 

 of the Cape hag-fish, taken off Cape Point at a depth of 

 175 fathoms. Both have seven branchial pouches and ten 

 teeth in each series, the two most anterior united. The 

 larger measures 320 mm. (93 mm. to the branchial aperture) 

 and the smaller 250 mm. (73 mm. to the branchial aperture). 

 The pores number 31 + 67 + 10 and 30 + 64+12 respectively. 

 Myxine capensis is nearest to M. australis, Jenyns, from 

 Chile and Patagonia, but differs from that species (and from 

 all others of the, genus) in having seven pairs of branchial 

 sacs instead of six. 



XXVII. — A new Species of the Crustacean Genus Thaumasto- 

 cheles. By W. T. Calman, D.Sc.

Travmastocheles zaleucus (Willemoes-Suhm), one of the 

 most remarkable of deep-sea Crustacea, was described from 

 a single perfect female specimen and fragments of a second 

 which were dredged by the ' Challenger ' off Sombrero Island, 

 West Indies, at a depth of 450 fathoms. In 1906 Dr. Doflein 

 referred to the same species a male specimen from Sagami 

 Bay, Japan, and four years later Miss Rathbun recorded a 

 female from a depth of 350 fathoms in the same locality. 

 Dr. Doflein mentions that Mr. Owston, the well-known 

 dealer in Yokohama, from whom "his specimen was obtained, 

 had previously sent another to England. This refers, in all 

 probability, to a specimen now in the Zoological Museum of 

 the University of St. Andrews, to which my attention has 

 been called by Prof. W. C. M'Intosh, F.R.S. I am greatly
