NO. 2 DEICHMANN: HOLOTHURIOIDEA; PARTII, ASPIDOCHIROTA 293 



was reported by Theel as early as 1886, and later by the Zaca and the 

 Arcturus, which also reported it from Costa Rica. Ludwig's Holothuria 

 maculate, from 66 fathoms off Cocos Island, refers to Jaegerothuria 

 inhabilis, while his Holothuria arenicola, from shallow water in Pan- 

 ama, is correctly identified. 



Strongly contracted specimens have occasionally been mislabelled 

 Holothuria impatiens, which occurs in similar localities, though prefer- 

 ably among rocks. Superficially the species resembles Lessonothuria 

 partialis, but the spicules are sufficiently different to prevent a misidenti- 

 fication.

Diagnosis: Medium-sized form up to about 15 cm long, rarely 

 longer. Often distinctly bottle-shaped with a long "neck." Feet in in- 

 distinct rows, large ventrally, more papilliform on the dorsum, often 

 placed on low round warts. Internal anatomy not remarkable; usually 

 with enormous thick tubes of Cuvierian organs. 



Spicules a crowded layer of stout tables, with eight large holes, about 

 as large as the central hole. Spire short, stout with one or two cross- 

 beams and a wreath of numerous short teeth on the top. Buttons smooth, 

 regular, usually with six large holes. Feet with end plate, smaller in the 

 dorsal appendages; supporting rods curved, with terminal holes, oc- 

 casionally with lateral holes, giving them the form of large buttons. 



Color mottled gray or brown, sometimes almost uniformly reddish 

 brown. Skin unusually sandy to the touch. 



Type: Undoubtedly lost. 



Type locality: Red Sea. 



Distribution: Almost circumtropical, common in the West Indies, 

 and ranging all over the tropical Indo-Pacific. In the Panamic region, 

 ranging from Colombia to the upper end of the Gulf of California, also 

 in the Galapagos Islands and Cocos Island. Most remarkable is that it 

 occurs on the west coast of Lower California, at Magdalena Bay and 

 Cedros Island.
