RADIATA. FISTULIDiE. Mulleria. 
Gen. VIII. MULLERIA. — This genus, contemplated by 
Cuvier, for the reception of the Holothuria fusus of ZooL 
Dan. X. f. 5, 6, and papillpsa^ ib. cviii. f. 5, I have 
presumed to inscribe to the memory of one of the most 
acute, industrious, and successful investigators of the tribe 
to which it belongs. 
16. M. digitata . — ^Tentacula twelve, ending in four obtuse 
branches. 
HoL dig. Mmit. Linn. Trans, xi. p. 22, tab. iv. f. 6. — Coast of Devon. 
“ Body long, cylindrical, covered with minute papillsa, of a yellowish- 
white colour, marked with small spots of red-orange closely disposed, and in 
many parts confluent.” The body contracts by numerous strictures. The 
discoverer of this species was inclined to refer it to the H, inhcerens of the 
Zool. Dan. tab. xxxi. 1-7, to which, in general appearance, it bears consider- 
able resemblance ; but he could not detect the longitudinal avenues of pa- 
pillae, which are very distinct in Muller’s species.
