It is more than probable also that Aristaeus armatus and Willemoesia indica 

 are meteoric (i.e. free-swimming or nectic) species. 



So that it would appear as if, of the 117 species of Macrurous Crustacea 

 known to inhabit the depths of the seas of India, only the following five are 

 truly abyssal : 



Acanthephyra microphthalmus, S. I. Smith. 

 Dorodotes reflexus, Spence Bate. 

 Pontophilus abyssi, S. I. Smith. 

 Glyphocrangon caecescens, Wood-Mason. 

 Pentacheles carpenteri, Alcock.
