116 THE APODOUS HOLOTHUEIANS 



Chiridota VIOLACEA. 



Chirodofa violacea Miiller, 1849, p. 379; 1850, p. 137. 

 Chiridota violacea Liidwig, 1892&. 



Length. — 300 mm. or more, with a diameter of only 6-8 mm. 



Color. — Not given, presmnably violet or purple. 



Distribution. — Reported from Ibo, near Mozambique (Miiller) ; Amirante 

 Islands (Bell). Semper ('69) gives "Zanzibar," but Ludwig ('99) says that is 

 probably a mistake, as Semper 's note apparently refers to Miiller 's original 

 specimen in the Berlin Museum. 



Remarks. — Although commonly attributed to Peters, the original descrip- 

 tion of this species is obviously by Miiller, and, so far as known, Peters never 

 published one word about it; there is no reason, therefore, why the name should 

 be written violacea Peters, even if that collector did select the name. Bell 

 ('84) is tbe only zoologist who has been fortunate enough to meet with this 

 sijecies since its original discovery, but unfortunately he does not consider that 

 fact sufficient justiiication for giving any information whatever in regard to the 

 siieciraen (or specimens?) collected by the "Alert." The large size of this 

 species and the number of digits make it an unusually interesting form. 



Chiridota m.^renzelleri. 

 Plate VII, Figs. 24, 25. 

 Chiridota vrarenzeUeri E. Perrier, 1904&, p. 370, with text figures. 



Length. — 33-36 mm., with a diameter of 10-11. 



Color. — Reddish above, deepest along the mid-dorsal region, with a network 

 of fine dark lines like cracks; yellowish white beneath. 



Distribution. — Reported only from Magellan Strait (R. Perrier). 



Remarks. — So well characterized is this species by its unique coloration, its 

 still more unique stellate calcareous particles, its few wheel-papilte (6 in one 

 and 9 in the other dorso-lateral interambulacrum), and its tentacles (having 

 only three pairs of digits, the terminal the largest), that one is almost inclined 

 to assign it generic rank; but, after all, the only character which would clearly 

 mark such a genus is the foi-m of the stellate bodies, and we are scarcely pre- 

 pared to accord that feature alone such distinction. 



Chiridota eximia. 



Chirodota eximia Haaoke, in Mobius, 1 (SSO, p. 47. 

 Chiridota eximia Liidwisr, 18926. 



Length. — Not given. 



Color. — Not given. 



Distribution. — Reported only from Fouquet's Reef, Mauritius (Mobius).
