3S ZOOLOGY OF THE VOYAGE OE H.M.S. SAMARANG. 



of this species is white, faintly marbled with grey ; the eyes are black, and there is a dark transverse band 

 across the middle of each tentacle. Operculum horny, semicircular, with the lines of growth distant. 



Hab. Java Sea. 



The Ranetta is by no means an inactive animal, but moves with considerable animation, 

 thrusting out its head, dilating its foot, and protruding its tentacles and sometimes its pro- 

 boscis with much vivacity ; it will even crawl with considerable facility up perpendicular 

 surfaces, supporting its somewhat weighty shell with comparative ease. In a species dredged 

 from twenty fathoms in the Java Sea, the very long extensile proboscis was exserted to the 

 distance of three inches from the head, and the animal appeared to employ it as an exploring 

 organ, moving it about in all directions. 



22. MUREX, Linnceus. 



1. Murex eurypteron. PI. VIII. Fig. 1 a, b. Eeeve, Conch. Icon. Murex, pi. 34. f. 176. 

 Hab. Japan. 



The shell here figured is only the second specimen yet discovered of this fine species, 

 and is remarkable for its elegant growth. 



2. Murex rorlfluus. PL VIII. Fig. 2 a, b. Mur. testa fusiformi, subventricosa, anfractibus trans- 

 versim obscure hratis, rugosis, quadrivaricosis, varicibus ruclibus, simpHcibus, planulatis, obscure denticu- 

 latis, aperture margine dentato ; sordide cinerascente, intus nigricante-castanea, varicibus albidis. 



Hab. Korean Archipelago. 



Chiefly distinguished by the simple character of the varices. 



8. Murex plorator. PL VIII. Fig. 3 a, b. Mur. testa trigono-ovata, anfractibus lsevibus, tri- 

 varicosis, varicibus compresso-alatis, apertura parva, rotundata, canali clauso ; castaneo-fusca, medio trans- 

 versim albizonata. 



Hab. Korean Archipelago. 



This shell is somewhat worn, but two or three specimens were collected, all having the 

 same characteristic form and dark chestnut colouring. 



4. Mtjrex Burnettii. PL VIII. Fig. 4 a, b. Mur. testa trigono-ovata, crassiuscula, anfractibus 

 transversim obsolete costatis, trivaricosis, varicibus late fimbriatis, dente unico marginali promineute, aper- 

 tura ovali, canali clauso ; albida, castaneo-fusco plus minusve tincta. 



Hab. Korean Archipelago. 



Another species from the same locality, of which two or three specimens were collected 

 in worn and broken condition. Each varix is furnished with a prominent tooth, the outer 

 varix being finely winged. The canal of the shell is closed over. We have the pleasure to 

 name this fine species in honour of Sir William Burnett, E.R.S.
