stumpy form of Purpura plicata, Mart. : " perfectly distinct," 

 teste Hani.] 



379. Conus arcuatus [as figured in Z. B. V., is a very different shell from 



that in Mus. Cum. and the monographs ; the latter is allied to C. 



tornatus], 



379. Conus interruptus [resembles the broad form of C. mahogani].

exarata, Nutt., teste Haul. The large specimens quoted are pro- 

 bably P. talcosa, Gld.] 



150. CJiama echinata. [Further series of specimens make it doubtful 



whether this be not a distinct species from C.frondosa, var. The 

 original sculpture has not yet been detected.] 



151. [Should be] Cytherea biradiata. 



152. (Add) Cardita borealis, Conr. (=="Arcturus rudis, Humphr.") pi. 44. 



f. 1. [Probably from near icy Cape. Mus. Belcher.] 



The types of the species described from this important voyage have been 

 scattered. Some have been identified from Admiral Sir E. Belcher's Collec- 

 tion, which he kindly allowed me to examine for that purpose ; others are 

 in the possession of Mr. Hanley ; but many appear hopelessly lost. 



29. Wood's Ind. Test. In Hanley's Revised Edition of this important 

 work (London, 1856), several new localities are added from the writer's 

 varied experience, and the synonymy is most carefully elaborated. No other 

 book contains such a mass of trustworthy information on the old species in so 

 small a compass. The following are quoted, either as original authorities, or 

 for locality or synonymy :
