si on of its known geographical distribution. It appears to be a bathy- 

 pelagic species, since both known specimens were taken by means of 

 deep-water tow nets. 



Genus EUCHAETOMERA G. O. Sars 



Euchaetomera G. O. Saks, 1884, p. 41 ; 18S5, p. 211. 



EUCHAETOMERA TYPICA Tattersall, 1926 



Euchaetomera typica G. O. Sars, 1884, p. 41; 1885, p. 211, pi. 37, figs. 1-20.— 

 Tattersall, 1926, p. 10. 



Occurrence. — Bermuda : Bache stations 10173, 200-0 meters, Febru- 

 ary 4, 1914, 3 specimens; 10187, 200-0 meters, February 23, 1914, 1 

 female ; both identified by Tattersall, 1926. Gulf of Panama : Alba- 

 tross station H2619*, identified by Ortmann (1894). Off Galapagos 

 Islands: Albatross station 4734*, identified by Hansen (1912). 



Distribution. — The record of this species made by me in 1926 is the 

 only one from American waters. I have also seen a specimen caught 

 at Bermuda and kindly sent to me by Dr. R. Gurney, by whom it was 

 collected ; the range now includes the Gulf of Panama and the Gala- 

 pagos Islands. The species is widely distributed in the tropical and 

 subtropical waters of the world. 



EUCHAETOMERA TENUIS G. O. Sars 



Euchaetomera tenuis G. O. Sars, 18S4, p. 42; 1885, p. 214, pi. 37, figs. 21-24.— 

 Ortmann, 1893, p. 23.— Colosi, 1919, p. 7 ; 1920, p. 23S.— Tattersall, 1926, 

 p. 10 ; 1936a, p. 96. 



Occurrence. — Western Atlantic: Bache stations 10173, off Ber- 

 muda, latitude 32°27' N., longitude 68°22' W., 200-0 meters, Feb- 

 ruary 4, 1914, 1 specimen; 10200, Straits of Florida, latitude 23°32' 

 N., longitude 81°48' W., 500-0 meters, March 18, 1914, 1 specimen; 

 10211, North of Bahama Bank, latitude 28°08' N., longitude 76°48' 

 Yi., 500-0 meters, March 22, 1914, 2 specimens. Galapagos Islands : 

 Albatross stations 4717*, 4719*, 4721*, identified by Hansen (1912). 



Distribution. — The type specimen of this species was collected by 

 the Challenger expedition at the surface off the coasts of Chile. Ort- 

 mann (1893) and Tattersall (1926 and 1936a) have recorded the 

 species from the Atlantic slope of eastern America and Colosi's record 

 is from the Galapagos Islands. No other previous American records 

 are known, but Bermuda, Straits of Florida, and north of the Bahama 

 Banks are now included. The species has a similar distribution in 

 the warmer waters of the globe to E. typica. 



EUCHAETOMERA PLEBEJA Hansen 



Euchaetomera plebeja Hansen, 1912, p. 202, pi. 3, figs. la-b. 



Occurrence. — Off Peru: Albatross station 4676* (type), identified 

 by Hansen (1912). 



Distribution. — Off Baja California and Peru.
