113. CONUS MACULOSUS. 



Co'/ius maculosus, Sow. 



C. macidatus. Sow. Thes. Comis, pi. 13. f. 296. 



In the ' Conchologia Iconica ' Mr. Reeve figures this species as 

 " var. b " of C. aneinone. Lam. (see pi. 25. f. 139 a). It is, however, 

 a very distinct species, as a comparison of a number of specimens in 

 various stages of growth tends to prove. C. maculosus is a nearly 

 smooth, thin, peculiarly inflated shell, richly mottled with purplish 

 brown, and attains a larger size than C. anemone, which is of a true 

 conical form, more solid, finely transversely striated, with an elevated 

 spire, and splashed with rose-brown or orange. C. anemone, more- 

 over, is an inhabitant of South Australia, and never occurs in Port 

 Jackson, where C. macidosns is to be found under rocks and large 

 stones, at low spring tides, in many situations. At Watson's Bay I 

 have taken as many as ten living specimens from beneath one stone. 

 This species is found in the Philippine Islands, on the authority of 

 the late Mr. Cuming. Length of the largest Port Jackson specimen 

 2|- inches. 



114. CoNUS JUKESI. 



Conns juJcesi, Reeve; Sow. Thes. Comis, pi. 13. f. 297. 



A very angular species, peculiarly mottled with bluish grey and 

 olive, first met with by Mr. Jukes during the voyage of H.M.S. 

 • Fly ' on the north coast of Australia. I have obtained several 

 fine living specimens (one of which was perfectly white) in Port 

 Jackson, in company with C. maculosus. Its maximum size is 

 1 inch 4 liu'vS.
