]9()<1] MOLLUSKS FROM THE VERSIAX GULF. 847 



Oi-aer Y. SEPTIBRAXCHIATA. 



Fam. CvsPiDAniiD.v.. 



Cl'SPIijaria approximata Smitli. 



C'tispidaria apprOMimata E. A. Smith, Ann. cfe ^h\if. Xat. Hist, 

 .ser. 6, vol. xviii. p. 373 (1896). 



P.G. Gulf of Oman, Ma.skat ; 10-1-5 fathoms, not scarce. 

 Also lat. 24° 49' X.. long. .56° 56' E. ; 225 fathoms. 



I. Lat. 15= 25' y., long 71' 45' E. ; 240 fathoms. 



This is piobahlv svnonvmons with C. hrachyrliynchits Stur. 

 (1899). 



CUSPIDARIA ALCOCKI Smith. 



CuspidMria alcocki E. A. Smith. Ann. & Mag. Xat. Hist. ser. 6, 

 vol. xiv. p. 170, pi. V. fig. 8 (1894). 



Cus'pidaria pjottl Sturanv. Experl. S.M. Schifl' ■ Pola ' in das 

 Rothe Meer (1899), p. 10, taf. i. figs. 10-16. 



P.G. Gulf of Oman. Lat. 25'-' 30' X., long. 57° 30' E. ; 

 85 fathoms. Lat. 25'- 51' X"., long. Se'" 54' E. ; 156 fatlioms. 



M.O. Lat. 25^^ 10' X^., long. 60' 34' E. ; 40 fathoms off Charbar ; 

 not infrequent in shell-sand. 



Small examples, apparently not full-grown, have so far only 

 been obtained in this latter locality. When adult, this is one of 

 the mo.st beautiful of the genus. 



CuSPIDARIA ELEGAXS Hinds. 



P.G. Gulf of Oman. Lat. 24'" 58' X.. long. 56' 54' E. ; 

 156 fathoms. 



Only in imperfect comlition, and very rai-ely occurring. 



We expected fully that the deep .seas of the Gulf of Oman 

 would have yielded more interesting Cuspidarue than has yet been 

 found to be the case. Dr. Sturany. for instance, described five 

 .species from the Red Sea (' Pola ' Expedition), two of which only 

 are in our gatherings. In all other families and genera tlie 

 results, we consider, come quite up to the highest expectations. 



In conclusion, we would express our best acknowledgments to 

 all those w^ho have in one way or another, through so many years, 

 assisted us in the preparation of this Catalogue : and would 

 primarily mention Mr. Edgar A. Smith. I.S.O.. Mr. Ei-nest R. 

 Svkes, F.L.S.. the late Dr. W. T. Blanford, F.R.S.. Dr. W. 

 Healev Dall, Dr. Rudolf Stiuany, Mr. Stephen Pace. F.Z.S., 

 Mr. A. J. Jukes-Browne, F.G.S.^ Mr. G. B. Sowerby. F.L.S., 

 Mr. A. Abercrombie, Mr. Hugh Fulton, Mr. J. Wilfrid Jackson, 

 Commander E. R. Shopland. Lt.-Col. H, D. Olivier. Miss Maud
