ACTINOPODOUS HOLOTHUEIOIDEA. 107 



Description :— Tentacles 20, white ; shields somewhat dark. 

 Length from 4—6 inches to 1 foot (120 mm. Theel). " Dorsum 

 fnscocinereum macuhs rotundato-angulosins, intensius coloratis 

 marmoratum. Hac maculae, in varus variae individuis, ad dorsi 

 latera inprimis conspiciuntur. Venter albidus dilute fuscocinereus " 

 (Jaegee pp. 18 — 9). " Thier weizengelb, auf dem Rücken mehrere 

 grosse, unregelmässige braunviolette Flecke " (Selenka 1867 p. 

 339). " Im Leben ist die Grundfarbe des Eückens gelbhchgrau, 

 die Flecken sind sehr unregelmässig und ziemhch dunkelbraun " 

 (Sempek p. 79). " Dorsal surface auburn, with some large spots or 

 bands of yellowish -white colour, ventral surface yellowish- white ; 

 here and there, especially along the sides of the body, a large darker 

 violet spot may be found within a light yellowish space. The am- 

 bulacral appendages have the shape of cylindrical pedicels, which, 

 however, are smaller on the dorsal surface. These pedicels are 

 supported by a well- developed terminal plate and numerous 

 transverse rods. Scattered among the dorsal pedicels other am- 

 bulacral appendages may be seen, which, being slightly larger 

 than the dorsal pedicels themselves, present an obvious conical 

 form, and may evidently be regarded as papilla). These papillae 

 are supported by a great number of rods, but their terminal plates 

 are very reduced." (Theel pp. 202—3). According to Selenka^ 

 the pedicels have the end-plate but are entirely without support- 

 ing rods. " Fiisschen ohne Stützstäbe, aber mit ästigen Körpern" 

 (Lamperï p. 87). " Die Kalkablagerungen der Haut bestehen aus- 

 schUesslich in rundlichen Ellipsoiden, auf der Bauchseite von 0,02 

 Mm. Grösse, auf dem Rücken, von 0,005 Mm. Durchmesser ; 

 durch Verwachsung dieser Körnchen entstehen oft liantel- oder 

 biscuitartige Formen" (Selexka 1867, p. 339). Sempee figures 

 very irregular, rather thick rosettes (Taf. XXX Fig. 10). Accord-
