several new species of Nudibranchiate Mollusca, 315 



lucid, broadisli in front, slightly arched and extending into broad 

 tentacular points at the sides ; tapering to a fine point behind. 

 Length If inch. 



One specimen of this fine species was dredged up in Torbay. 



Eolis inornata. Body ovate-oblong, rathfer depressed, tapering 

 to a fine point beiiind. Oral and dorsal tentacles rather short 

 and thick, nearly of the same length ; the first white, the others 

 yellowish and slightly wrinkled. Back pale fawn-coloured or 

 nearly white. Branchise cylindrical, tapei-ing to an obtuse point, 

 set in eight or nine rows of four or five papillse each ; of a dull 

 brownish orange freckled with brown and white : apices for some 

 distance transparent white, with the ovate vesicle of a more opake 

 white seen distinctly through. Foot white, expanded in frotit, 

 curved and extended into points at the sides. Length ^ths of 

 an inch. 



Under stones near low- water mark^ Torbay. When in motion, 

 the branchise nearly cover the whole of the back* This species 

 is allied to E. angulata. 



Eolis punctata. Body yellowish, inclining to flesh-colour on 

 the back, covered with largish opake white spots. Dorsal ten- 

 tacles yellow, thickish, tapering and truncated at the top ; lami- 

 nated with twelve or thirteen oblique folds sloping downwards 

 behind as in Doris. Oral tentacles very long and tapering. 

 Branchise nearly linear, tapering to a fine point ; of a yellowish 

 brown colour spotted with white, arranged in five or six clusters 

 down the sides of the back, the first and second^ large, the rest 

 small and confluent, extending nearly to the tail. Foot nearly 

 linear, the front bow-shaped and extending into tetitacular points 

 at the sides. Length nearly an inch* 



Dredged in deepish water, Torbay. 



This Eolis is peculiar from the shape of its dorsal tentacles 

 and the conspicuous white spots with which it is entirely covered^ 

 It is allied to the Eolis Drummondi of Mr. Thompson. 



Eolis tenuibranchialis. Body fawn -coloured or yellowish, rose- 

 coloured near the head. Dorsal tentacles orange tipped with 

 yellow, and ringed with numerous small lattiinse. Oral tetitacles 

 rather longish and thick at the base. Branchise sinall and very 

 slender, linear, of an olive colour tipped with opake white ; set in 

 seven clusters down the sides of the back, the first three distinct, 

 the others coalescing. The back in the region of the stomach is 

 of a dark purplish colour. Foot with a deep transverse slit in 

 front and extending into tentacular processes at the sides. Length 

 an inch and a quarter. 



A single specimen in a sickly state was dredged in Torbay and 

 died very soon afterwards. 



Allied to E. Drummondi.
