without doubt to the species described by Pallas. It agrees in every 

 detail with the account given by that author and also equally well, as 

 Jordan and Gilbert say, with ChirolopJtvs japonicus of Herzenstein. 

 The specimen figured by Bean differs from the one described by Pallas, 

 as is shown in the following pages. That described by Jordan and 

 Starks and indicated as the type of the genus Bryostemriia is identical 

 with the form figured ))y Bean. It becomes the type of a new species, 

 Bryostennma decoratunt. Of the specimens collected bv the U. S. Fish 

 Commission steamer AJhatross in Alaska, and recorded ])v Jordan and 

 Starks and later by eJordan and Evermann, the one having ""the cheeks 

 covered with densely matted cirri " proves to be a new species, Bryos- 

 temma tarsodes. The others cited as young examples belong to a dif- 

 ferent genus, now recognized for the first time as Bryolophv'^. The 

 ospecies being new, ma}^ be known as Bryolopkvs lysimus. 

 Descriptions of the new forms are here given.

Fig. 1.— Bryoste.mma tarsodes. 



Interorbital space broad, convex; snout short, jaws equal; maxil- 

 lary extending to a vertical through posterior border of orl)it. Teeth 

 rather strong, acutely conical, placed alternately in 2 closely apposed 

 rows, the points nearly aligned in a single cutting edge; no teeth on 

 vomer and palatines. Gill-membranes forming a broad fold across the 

 isthmus. Pseudobranchia3 large; gill-rakers on first arch about 15, 

 short, broad, pointed, close together. 



Body covered with minute scales, the head naked; membranes of fins 

 without scales. Lateral line represented bv a short row of 5 pores 

 above the gill-openings, the pores concealed by papilla?. Cheeks, 

 snout, and whole upper part of head closely covered with tentacles and 

 papillfe. Snout with a median branched tentacle; upper border of 

 orbit with three large, branched tentacles, the first not united with its 

 fellow of the opposite side, the second highest, its length equal to 

 vertical diameter of the ej^e, third short and club-shaped; on the
