Hab. Stations 9 and 17.

41. MuREX (Cerastoma) emarginatus, Sowerby. 



Murex e^narginatus, Concb. lUust. figs. 98-100; Reeve, Coucb.

Hab. Stations 4 and 11. Kiusiu {LischJce). 



Tbe operculum is subpyriform, baving tbe nucleus at tbe outer 

 side at a short distance from the lower or smaller extremity. On 

 the lower surface it has a smooth thickening along the outer edge, 

 and tbe marks of muscular attachment consist of a few narrow 

 concentric layers placed obliquely crossways. It is of a reddish- 

 brown colour, paler at tbe outer margin. 



42. Murex (Cerastoma) rorifluus, Adams & Reeve.

f. 2 a, 2 5. 



Murex moiiachus, Crosse, Journ. de Concb. 1862, vol. x. p. 55, 

 pi. 1. fig. 8. 



Hab. Station 4. Bay of Talienwban, N. China {Crosse); Tsau- 

 lian {A. Adams, P. Z. S. 18G2, p. 3/3); Nagasaki (LischJce). Korean 

 archipelago (Samarang). 



Crosse refers to the similarity of his species to M. rorijluus. The 

 type of the latter is now in tbe Museum, and appears to me a very 

 worn specimen of the same species described as monachus. 



Tbe specimen figured by Crosse is in bad condition and does not 

 truly represent the usual character of the colour of Japanese speci- 

 men's. In these tbe ground-colour is a dark chocolate-brown, which 

 is interrupted by narrow transverse whitish lines, two in number on 

 the upper whorls, and varying from four to eight on the last ; they 

 are a trifle elevated, especially upon the varices. Tbe latter vary in 

 number, sometimes being four on a whorl and sometimes five. All 

 the eleven specimens from the Goto Islands are smaller than those 

 from Talienwban, and rather narrower. Owing to tbe bad state of 

 tbe shells, Crosse was not enabled to notify the presence of a very 

 short tooth-like projection near the base of the labrum. It is very 

 small, but still is constant in all perfect shells. The operculum is 

 almost precisely the same as that of the preceding species. 



43. Murex (Muricidea) cirrosus, var., Hinds. 



Murex cirrosus, Hinds, V. Z. S. 1843, p. 128; Voy. Sulphur, 

 3. p. 9, pi. 3. f. 17, 18; Reeve, Concb. Icon. i. fig. 138. 



Hab. Station 2. Straits of Macassar {Hinds) ; Andaman Islands 

 {Capt. Wilmer). 



The single specimen obtained by Capt. St. John oft tbe coast of 

 the Goto Islands is remarkable for the manner in which tbe trans- 

 verse lirae at the upper part of the whorl are produced at the varices
