*Tlie Eui'opean Hagfish (M. ghitinasc) and the American Hagfish {M. limosa) have long been regarded as forms 

 of one and the same species. Characters wliich specifically diagnose them have been pointed out in "A Revision 

 of the Myxinoids of the Genus Myxine," by Mr. C. Tate Regan, and are here quoted: — 



Myxine glulinosa. 6 (exceptionally 7) branchial pouches. 7 to 9 teeth in the first aeries and S to 10 in the .second, the 2 most 

 anterior teeth in each series united. Pores 24-34 + 54-64+10-14. Length of head 3f to 4 in the total length. 



Northern and western coast of Europe. 



Myxine limosa. 6 branchial pouches. 9 teeth in the first series and 10 in the second, the two most anterior teeth in each 

 series united. Pores 26+70+10. Length of head 3J in the total length. 



Atlantic coasts of North America 

 It may lie mentioned that in the "Revision" there is also a diagnosis, quoted below, of a new species M . 

 iillaiilica from western North Atlantic, although it may not be indigenous to the coasts of t'anada. 



Myxine allanlica.n. sp. 6 branchial pouches. 9 teeth in the first series and 8 in the .second, the two mo.st anterior teeth in each
