3 specimens of 7 — 23 cm. length. Among stones at the shore. Masatierra 

 ^74. 1917 (K. Backstrom). Further there are 6 specimens from the same island, 

 collected among boulders in Bahia del Padre by C. Skottsberg ^^/s 1908 

 (Swed. Magell. Exp. 1907—09.) They agree in every respect with the detailed 

 description, given by LUDWIG, to which I have nothing to add. It may, 

 however, be desirable to give a figure of one of the larger specimens, LuDWlG 

 having figured only the spicules.

 Holothurien d. Sammlung Plate. Zool. Jahrbucher; Suppl. IV, p. 446—448. 



Cumberland Bay 20—25 m., Masatierra, V12 19 16 (K. Backstrom). 

 Clay. 4 small specimens, ^U — i ^/a cm. long, colour white. 



The identification of this Synaptid is not beyond doubt as the calcareous 

 deposits have been totally dissolved, on account of preservation in formalin. 

 Its general shape, however, makes it highly probable that it is this species, 

 which was described by LUDWIG from this locality.
