2 ART. 2.— BASHF0RD DEAX. 



In addition to the myxinoids above referred to, the present 

 writer during a stay at Misaki, as a guest of the Marine Laboratory 

 of the Imperial University of Tokyo, was able to secure two unde- 

 scribed species, one of which is remarkable for its large size, and in 

 the possession of eight gill openings, the only myxinoid, indeed, in 

 which this number is known normally to occur. The second pre- 

 sents characters closely transitional from Homea to Mijxine and is 

 regarded as representing a new genus. These forms are described on 

 the following pages and reference is made to the eggs of three 

 myxinoids and to the breeding characters of the common Homea 

 bargen. 



The present studies were carried on largely at the marine station 

 at Misaki, and partly at the Zoological Institute of the Imperial 

 University of Tokyo. In both of these laboratories every facility 

 was generously granted me, and I wish to acknowledge with especial 

 gratitude the many courtesies of their director, Professor Kakichi 

 Mitsukuri. My thanks are also due to Professor S. Watasé of the 

 Imperial University, for his kindness in editing and publishing the 

 present paper, favors which I especially appreciated in view of the 

 difficulties attending proof-correction when an author is distant half 

 way around the world. 



HOMEA BURGERI. 



This species is taken in large numbers in shallow water in the 

 small bays in the neighbourhood of the marine station at Misaki. 

 Most of the specimens I examined were taken in water of three or 

 four fathoms, and they occur in even shallower, for I have seen them 

 near the stone steps of the laboratory. In this region specimens 

 were obtained throughout the year, save during an interval of several 

 weeks (September and October), when the fish were found to be
