 to 195 fathoms, March 8, 1933, 1 specimen (type). 



Distribution. — West Indies and the Bahamas. 



Remarks. — The material is not in a very satisfactory condition and 

 is composed mainly of small specimens 6 to 12 mm. in length. I have 

 already recorded the material and discussed it in my earlier paper. 

 In the light of what is written above under P. glaber I am not satis- 

 fied that the species is well founded. I reproduce my earlier figures 

 illustrating this species (fig. 2, b, c). 



Genus GNATHOPHAUSIA Willemoes-Suhm 



Gnathophansia Whxemoes-Suhm, in Thomson, 1873, p. 400.

Occurence. — California : Albatross stations : 2937, 1 male, 57 mm. ; 

 2839*, 2919*, 2923*, 2929*, 2936*, 2980*, 2986*; specimens from the 

 following Albatross stations were identified by Ortmann (1906) : 

 3127*, 3348*, 3627*, 3670*, 4335*, 4337*, 4354*, 4528* ; specimens from 

 Albatross station 3681* were identified by Hansen ( 1912) . Philippine 

 Islands: Albatross stations: 5638, 1 male, 71 mm.; 5650, 1 male, 76 

 mm. Hawaiian Islands: Albatross stations: 4109*, 4142* identified 

 by Ortmann (1905). Gulf of Mexico: Albatross station 2384*. 



Distribution. — Ortmann (1906) records a single specimen from the 

 eastern waters of America, in the Gulf of Mexico in 940 fathoms. He 

 gives a long list of records from the western American coast. The 

 specimen from station 2937 is from the west coast of California and 

 therefore supplements Ortmann's earlier records. The other two 

 specimens are from the waters around the Philippine Islands, from
