1906.] MOLLUSKS FHOJI THE PERSIAX GULF. 787 



Pandorce, two Thracke ; these last were both discovered in recent 

 years — one by Commander E. R. Shopland at Aden, and now re- 

 corded with increased disti'ibution in the Pei'sian Gulf ; the other, 

 first found by Mr. A. Abei'crombie, near Salsette Island, Bombay, 

 is not yet known outside that restricted limit. Finally, among 

 the Septibranchiata are to be seen a few Cuspidarice [Necerce). 

 Doubtless, further deep-sea dredgings will increase the number 

 here, the present records being somewhat below the average. 

 Recently, Dr. Sturany has discovered in Erythrtean watei-s no 

 less than five species of this genus, two of which (C /^oiit 

 and hrachyrhynchus Stur,) are among the enumerations in the 

 accompanying Catalogue, both antedated by the names C. alcocki 

 and approxmiata E. A. Smith, having been first dredged by the 

 s.s. ' Investigator ' Expedition in the Bay of Bengal.
