308 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 11 



The species living normally at remarkably great depth, 50 to 250 

 fathoms, rarely at 10 to 14 fathoms or less. 



Type species: Holothuria lentiginosa v. Marenzeller. 



Remarks: In this genus has been included a number of species that 

 Panning, in his revision, scatters in different groups. The oldest is the 

 type species, known from the eastern Atlantic and the West Indies; 

 next come Holothuria Integra Koehler and Vaney, from the Gulf of 

 Bengal, and H. neozelanica Mortensen, from New Zealand, (possibly 

 a synonym of H. Integra) ; and finally H. zacae Deichmann, from the 

 Panamic region. With some doubt, I have also included H, minax 

 Theel, from 10 to 14 fathoms, in Japanese waters, a well characterized 

 species and not a synonym of Stichopus gyrifer (Selenka) {= Holothuria 

 monacaria of Panning and others).
