Body about half an inch long, nearly linear, slender, smooth, semitransparent, pale 

 yellow or buff, spotted with reddish or brownish purple. The spots usually form a broad 

 interrupted line from the front of the head almost to the tail ; from this, belts of similar 

 spots pass transversely between the branchial processes and blend with a line of spots that 

 passes along each side. Tentacles filiform, truncated at the tip, and transparent, issuing 

 from rather long trumpet-shaped sheaths; wide at the top and more produced anteriorly; 

 set near together at the base and diverging above. Veil entire, straight in front, produced 

 and rounded at the sides, and capable of extension and contraction in a lateral direction. 

 Branchia from five to seven pairs ; the last frequently rudimentary, the rest nearly of equal 

 size, large in proportion to the animal, elliptical, pedunculate and muricate, semitransparent, 

 having four or five circles of tubercles and a terminal one at the apex : the tubercles are 

 capable of extension and contraction, and each is surmounted by a dark red spot, sometimes 

 nearly black. The central portion of the branchiae is generally of a brownish rose-colour, 

 sometimes purple-brown, and occasionally pale buff or olive. Foot transparent white, 

 tinged with yellow, rounded and somewhat bilobed in front ; the margin slit transversely ; 

 ending in an obtuse point behind. 



The heart forms a slight swelling on the back, between the first and second pairs of 

 branchial processes. It pulsates 60 times in a minute. 



This is a very beautiful and delicate little animal. It is liable to great variation in 

 colour, and the spots are frequently jagged, and produced into streaks. The body is occa- 

 sionally almost colourless, and nearly devoid of any sort of markings ; and we have seen it 

 entirely of a beautiful rose colour, with the body nearly covered with confluent purple or
