48 NOTES ON A COLI.RCTION OF CALIFORNIAN NUPIARANCHS. 



spines, which may either represent a stomachic armature or be merely the 

 remains of some animal whic:h has been swallowed. They were ncjt 

 observed in any place to be clearly arranged on the walls of the stomach. 

 The liver is deeply grooved to receive the intestine which is whitish. It 

 runs low down at the side of the liver and turns upwards at the end of the 

 body. 



On the anterior surface of the liver are seven yellowish grey lobes 

 which appear to constitute the hermaphrodite gland though they are so 

 much hardened that the structure cannot be clearly seen. In any case they 

 do not form a layer over the livei, nor do they extend to the posterior part 

 of the body cavity. The genitalia are not well preserved, and, as it would 

 seem, not fully developed. The mucous gland is of moderate size aud the 

 spermatotheca appears to be elongate. The distinct, yellowish renal syrinx 

 lies at the side of the intestine. 



Prof. MacFarland informs me that this species found by Mr. Cockerell 

 at San Pedro is common at Pacific Grove. The living animal is of a light 

 brown, plentifully besprinkled with fine lemon yellow spots, and with a 

 single pink spot at the base of each papilla. The shape of the living 

 animal is rei)resented in figure 8a. In alcohol it becomes unnaturally high 

 and square and the thin expanded edge of the foot is lost It further 

 appears from Prof. Mac Farland's notes that the glands penis is armed but 

 not the stomach, so that the spines found by me must be part of some 

 animal which had been eaten, and that the undivided character of the liver 

 is constant in all specimens. 



JanolUS, Bergli. 



This genus, which was created by Bergh for Janolu^ ausfrali,-! obtained 

 by the Challenger in the Arafura Sea, differs from Antioijdia^" (Jaim>i) in 

 havino- large smooth jaws and a very wide foot with an expanded margin. 

 Antiopella hijaUna has been shown by Bergh to be referable to this aenus 

 and a new form is here described, so that the known species are : —

Found at Dead Man's Island, San Pedro, California. 'I'he notes on the 

 living animal say that it looked like a mass of speckled jelly, and that the 

 cerata were very easily deciduous. The colours are to be gathered from the 

 sketches (figs. 12, 13).
