discovery in the towings was almost accidental. We spent much 

 time looking for others but with no success. The spine-hearing pro- 

 cesses with which this species is covered serve to distinguish it from 

 all other species of the genus. 



In placing these last two species in Ammothella, I have followed 

 Cole, who raised the sub-genus Ammothella (Ammothea part), of 

 Verrill, to generic rank because of the trunk being "usually propor- 

 tionately broader and distinctly segmented, the chelifori three- 

 jointed, and the palpi nine-jointed." I hope that this brief explana- 

 tion will show why they are not Ammothea proper, and avoid con- 

 fusion. The multi-spine bearing processes on A. spiitoxixxinid may 

 remind one of those on a Nymphopsis figured by Loman, Plate XIII 

 of Siboga-Expeditie XL, but the arrangement of these processes, as 

 well as generic characters, show that there can be no possible con- 

 nection.
