Distribution. Distributed over the Indo-Pacific region of the 

 tropical zoDe from as far W. as Mozambique (' Alert ') to as far 

 E. as Society Is. 



Two specimens from Eotuma, the largest being 91 mm. x 30 mm., 

 seem to resemble in every respect the specimens collected by 

 H.M.S. ' Challenger ' and described by Theel, p. 201. They differ 

 from the specimen described by Lampert from the Lucepara Is. 

 in the absence of the arrangement of ventral feet in rows, although 

 patches occur on the ventral surface, where the feet are less closely 

 arranged than elsewhere.

Reference. Theel, ' Challenger' Holothurioidea, ii. p. 201. 



Distribution. The species has been recorded from Fiji, Grreat 

 Barrier Reef, Amboina, Thursday Is., Celebes, Sumatra, and Indian 

 Ocean (Seychelles) ; it is thus fairly \\'idely distributed over the 

 Indo-Pacific region of the circum tropical zone. One specimen 

 from Kotuma, -±0 mm. x 15 mm., appears to belong to this species. 

 It resembles Theel's description of the Fiji specimen in every 

 particular except in colour, which is whitish brown with a few 

 irregular dark patches on tbe dorsal surface ; the ventral surface 

 is lighter than the dorsal, and the tube-feet and papillge are darker 

 than the ground-colour. 



The anal teeth are quite visible to the naked eye, and the 

 deposits are like those described by Theel, except that they appear 

 to have undergone a certain amount of soluticm and in consequence 

 the identification is not certain.

Distribution. The species thus constituted is one of the most 

 widely distributed circumtropical forms : it is recorded from the 

 West African region (Madeira), East American region (Florida), 

 and greater part of the Indo-Pacific from Seychelles Is. to Samoa, 

 including the lied Sea. 



A large number of specimens from Funafuti lagoon 20 fathoms 

 and from the " mangrove swamp," largest about 25 mm. X 7 mm. 

 As the specimens combine a number of characters of A. parvula 

 and A. jiavomstunea it seems worth while to describe them some- 

 what minutely. Theel has himself suggested the possibility that 



' Hoi. sp. n., ? juv., described by Liidwig (Zool. Jahrb. Sjst. iii. p. 808, 

 figs. 1-5), eeems to be closely allied to this species, although no mention is made 

 of anal teeth and it appears thus to be a true Holotharia.
