3S6 MOLLUSKS OF THE (JALAPAGOS — STEARNS. 



35. Conus pyriformis lvvt>. 



A sin.ulo example (Mus. No. 102341'). 

 Hood Islaiul. 



36. Conus iiux Hrod. 



Beacli shells. 



Hood (102;>tr)) and Jaiiies islands (102271). 



Exceedingly close to the Indo-i'acilic species (Jci/loncnsis Ilwass., 

 which latter includes according^ to Tryon the synonyms ^msiZ/m* Gould, 

 acutus Sow., ^)/^s'//^M.s (Chemn.) auet., tcnnisKJcatxs 8ow., uponsaUfi 

 Cliemn., iiauu.s r>rod., to allot which, excepting- CJouUVs, Tryon j^ives a 

 varietal i)»sition. Tryon includes the west coast shell in the synonymy 

 of Cei/Joiicnsis, but whatever may be tlie oi)iMi()n of others on this point 

 Broderip's name may conveniently be retained for the West American 

 shell. Found at Chatham Island by Dr. Jones. 



37. Conus gladiator Urod. 



One example, beach, (102273.) 



James Island. 



Mr. Tryon comments on (he closeness of this form to hrunncus. 1 

 have at various tinu'S possessed and haiulled a lariat' number of speci- 

 mens, but have never been imi)ressed by any such resemblauce. 

 38. Conus Fergusoni. Sow. 



Several specimens, bciich. 



James Island (No. 102270) ; Iiulefatigable Island No. 102450). 



This rare species seems to have its home in the (iahipagos islands. 

 The original example, r>:| inches in length, was said to have been col- 

 lected at Panama. Some seven or eight S])ecinu'ns were obtained by the 

 Albatross, four of them at Indefatigable Island. The largest of these 

 was 4§ and the smallest 2^ inches long. One of them was quite fresh, 

 Avith epidermis intact. Notwithstanding its large si/e, it is (piite un- 

 attractive, being a coarse white species without the slightest ornamen- 

 tation. 



The Oahijuigos islands, or rather certain of them, ai)i)ear to be the 

 specific center of a few marine forms, and a few other species here at- 

 tain, in tlie matter of size and solidity, a remarkable development. 

 Anuuig the (^)nes C. Fcrfiusoiii, exceedingly rare on the mainland and 

 so seldom nu't with in collections, is not infrequent ou Janu's and In 

 defatigable islands; so with (^onuspurpumscens and the variety of the 

 same known as (\ nrjalittifKs, which are found at several of the islands. 

 The interesting and variable ('. hnanicKs, with its characteristic yet ex- 

 treme varieties, has its metroiudis in the Galapagos group. So also 

 with Mure.viPhi/Uonoius) princrps, PHrpurK mclo, P. planospira, F.patn- 

 la and its ch)se relative /'. columrUarls. Cassis tenuis here attains a 

 vigorous growth and fre(iuently an extraordinary size and solidity; 

 Cifprcva nif/roptfuctata is common, elsewhere -lixceedi ugly rare, and so 

 with many other less cons})icuous forms.
