and described by Coutière in 1905, have perhaps been taken, for a part, between 30 and 

 50 fathoms. Some species have been obtained at a somewhat greater depth not exceeding, 

 however, 150 m., except 2 or 3 that are living in considerably deeper water. These are, in the 

 first place, A. Shearmei Alc. & Anders., the unique specimen of which was collected off the 

 Travancore coast at a depth of 430 fathoms. The second, A. macrosceles Alc. & Anders., has 

 been observed in the Bay of Bengal in water of 193, 145 — 250 and 270 fathoms and in the 

 Andaman Sea, at a depth of 188 — 220 fathoms: the egg-bearing female, which was taken at 

 Stat. 5 and referred with some doubt to this species, was obtained at a depth of 330 m., 

 the bottom being mud. At a depth of 289 m., Stat. 12, another ovigerous female was collected, 

 unfortunately in such a mutilated condition, that it remained doubtful whether it belongs to the 

 variety leptopus of A. uialabaricus Fabr. or not. 



The other species taken in water deeper than 30 fathoms are the following : 



A. Hailstonei Cout. var. assimitlans de Man, 90 m., 113 m. and less. 



A. Hailstonei Cout. var. lactabilis de Man, 34 m., 70 m., 73 m. and from 400 — 120 m. 



A. Amirantei Cout., between 25 and 80 fathoms. 



A. Providencei Cout., between 50 and 78 fathoms. 



A. paralcyone Cout., 8 m., 45 m., 70111. and 113111. 



A. spongiarum Cout., 8 m., 13 m., 15111. and 113111. 



A. Eulimene de Man, 83 m. 



A. bidens (Oliv.), 13111., 83111. 



A. Percyi Cout., between 25 and 50 fathoms. 



A. dasycheles Cout., 37 fathoms. 



A. gracilipcs Stimps., 32 m., 83 m. 



A. teiuiicarpus de Man, 75 m. and less. 



A. sp. de Man, between 54 and 90 m. 



A. tcnuipes de Man, between 75 and 94 m. 



A. lepidtts de Man, 75 m. and between 54 m. and 90 m. 



A. Sibogae de Man, 70 m., 113 m. 



A. acutocarinatus de Man, 72 m. and less. 



A. prosettchirus de Man, 72 m., 75 m. 



A. pareuchirus Cout., 32111., 36111., 57 m. and 90111. 



A. pareuchirus Cout. var. Letuolhea de Man, 15 m., 70 m. and 54 — 90111. 



A. pareuchirus Cout. var. imitatrix de Man, 18 m., 32111., 113111. and 141 m. 



A. leptocliiroides de Man, 90 m. 



The new A. bicostatus de Man has been taken, besides on a bottom of coral, coralsand 

 and Lithothamnion, also, in Buton Strait, between floating seaweed. The other species were 

 taken in water, the bottom of which consisted of living or dead coral, coralsand, shells, 

 Halimeda, Lithothamnion, often of black sand or mud or mud with sand.
