spines to its tip 10.0; len^rth of snout 9.5; diameter of eye 7.6; distance 

 from tip of snout to posterior edge of maxillary 9.7; distance from 

 tip to snout to origin of dorsal 28.8 ; snout to origin of anal fin 48.5 ; 

 snout to insertion of pelvic fins 24.7 ; distance from posterior edge of 

 anal fin to midbase of caudal fin 21.2; least depth of caudal peduncle 

 6.7; length of longest or first spinous ray of dorsal 42.3; length of 

 longest or last ray of soft dorsal 26.6 ; length of longest or last ray of 

 anal 19.8 ; length of longest ray of pectoral fin 21.9 ; length of longest 

 pelvic fin 27.7; length of caudal fin 33,2; width of body at rear of 

 head 16..5; interorbital space 1.6. 



Dorsal fin IV — 8 ; anal 7 ; pectoral R. 17 — L. 18 ; pelvics 1, 5 ; caudal 

 10; about 6 or 7 gill rakers on first gill arch. 



Head depressed, the snout depressed and flattish, a trifle concave; 

 snout projects a little beyond lower jaw, the latter below the premaxil- 

 laries, which when retracted do not extend quite to the tip of the 

 snout ; villiform teeth on premaxillaries in two large patches each side 

 at front of jaw, then a toothless space followed by a narrow band of 

 villiform teeth; lower jaw with a narrow band of villiform teeth; no 

 teeth on vomer or palatines; the free dermal flap at rear of head 

 nearly equals the diameter of the eye. 



The gill membranes are joined to the shoulder and isthmus so that 

 the gill opening consists of a small round pore; the pelvic fin has I 

 spine and five branched rays; the last ray has a membrane that joins 

 the base of the pectoral fin at the fifth ray ; body somewhat triangular 

 in cross section, the lower lateral-ventral angles each with a fleshy 

 or dermal keel commencing opposite origin of anal fin and continu- 

 ing to caudal peduncle ("dermosteira") ; eighth ray of pectoral long- 

 est; lateral line begins a little above gill opening and continues 

 somewhat arched above the pectoral, then just behind tips of pectorals 

 continues along the midaxis of the body ending at the base of the 

 caudal fin, along the lateral line at irregular intervals are very short 

 canals coming off at right angles ; the "dermosteira" does not appear 

 to be associated with a lateral line canal; anal papilla simple; 

 peritoneum white. 



Color pale with numerous faint areas of blackish pigment, these 

 arranged irregularly but in more or less of a row of faint spots along 

 lateral line and along the "dermosteira"; anal fin pale dusky, the 

 tips of the rays white; caudal with five faint bars. In life the color 

 was mostly white and pinkish shades and light greenish above. 



Remar'ks. — This new species differs from all other callionymids in 

 the presence of the "dermosteira" along each side of the body. 



Named dorotheae in honor of my wife, Dorothea Bowers Schultz, 

 who has helped me in numerous ways in connection with my ichthy- 

 ological studies.
