left-hand side of the free-oviduct beneath the penis. In figure 14 

 (PI. iv), the free-oviduct is purposely omitted so as not to complicate 

 the figure. The extreme end of the receptaculum seminis is over- 

 lapped by the folds of the oviduct. The penis is long an.d twisted 

 upon itself (PI. iv, fig. 14, p.). At the point where the penial retrac- 

 tor muscle is attached, its walls are thrown into a series of 

 constrictions and at the distal end of this constricted portion there is 

 a short coiled kalk-sac (PI. iv, fig. 13, /r.-s-.). The vas deferens passes 

 over the proximal portion of the penis and then beneath it before 

 communicating with the ov'duct. No flagellum or diverticulum was 

 present in the specimen dissected. The penial retractor muscle is 

 long, and originates just behind the right tentacular retractor muscle 

 on the right posterior border of the visceral mass. The free oviduct 

 is much longer than in (r. hookeri, Gray, but not so wide. The 

 common duct is a sinuous tube, but not folded upon itself as in many 

 species of this genus ; lying over its posterio-dorsal portion is the 

 albumen gland. I was unable to trace the hermaphrodite gland, but 

 a portion of the hermaphrodite duct was dissected out; this is character- 

 ised by the absence of any convolutions or foldings so generally 

 associated with this particular organ (PI. iv, fig. 13, h.d.).

One specimen. 

 The habitat of the type was Mergui. Mr. Edgier A. Smith, who has 

 very kindly examined this specimen and compared it with examples in 

 the British Museum, writes me " We have a specimen from King 

 Island, Mergui Archipelago (named by Dr. von MdirtensdiS resplendens) 

 which is exactly like your example only a trifle smaller, that is to say 

 less fully grown."
