CouvM., III., liju. 10) are the tiaratm I hod. described by the author from 

 (iiilai»agos exaiii[)le8. Pale-colored speeiiiieiis with a facies intermedi- 

 ate with these have l)een credited to the' Indo-Paeific species miUaris, 

 or rather this hist has been credite<l to th<' (liilapa^os Islands thron/.;h 

 the general and often (piite elos(^ resend)liuu;e of individuals fiom these 

 widely sei)arated rep^ions. Th(^ variety of />ru//wr»s resembling miliuriH 

 was obtained at both Hood and Duncan islands. Another Indo- 

 raciflc cone, C. minimus 'auct., has been wronj;ly leterred to these 

 islands, the exeeedinjn" variableness of 6*. brunneus and the erroneous 

 determinations of authors havin<»' br(mj>ht about this confusion. Thus 

 Keeve says, in his Mono<;i!iph of the cones, "there <'an be no doubt of 

 Mr. Broderi|)'s C. tiuriUm beiuft* a variety ot minimus; they exhibit too 

 mauy characters in common to allow of their being sei)arated." Cum- 

 ing collected the Droderip format the 'K}alaj)agos Islands, found in 

 pools on the sands." Subse([uently at the end of his Monograph, Keeve 

 changed his mind and admitted Broderip's tiaratus as valid, but failed to 

 observe its relationship to bnmneus. Tryon also fell into the error of 

 including tiaradis in the synonymy of wi/7m>/.v, and in this way crediting 

 the latter to the Galapagos Islands. Keeve also (Monograph of the 

 Cones, 1*1. XLi) adds to the confusion by fig. 224, " C. varius B., Gala- 

 pagos Cuming," which figuic, sim[)ly ju'cscnts a Xiuivty of h run u ens and 

 ('orre8i)()nds to two exam ])l(\s collected by J)r. Jones at Manta, Ecuador. 

 Cunn'ng found this shell in clefts of the rocks at low water. It has 

 been iMonogiai»he(l with v(a-ins, an Indo-1'acitic species, as '•'■ imlvhellus 

 Sby., non-Hwainson, and intrrruptus Wood." 



A conmion aspect of (j. hrimncus is of a uniform sienna-yellow with 

 a i'aint median band and i)nrplish at the base of the ccdumella. The 

 scidi»ture, as IwA'am intimate*!, varies considerably in sharpness, and 

 this applies as well to the gianuhis on the main whorl as to the coro- 

 nation of the spire. 



The importiuujc and advantage of a large scries of a species such as 

 \\\iit of C. brunucus in the national collection are obvious when cpics- 

 tions of identity and distribution are involved, as in the foregoing 

 instance. 



The synonymy also through error includes, as my remarks show, 

 miliaris, minimus, and varius B., all IndoPaciftc forms. While many 

 forms of a decid<Ml Indo-I*acitlc character do occur on the west coast of 

 ^oith America, 1 have as yet failed to detect a single Galapagos sp(^ 

 cies that does not exhibit as close or closer relationship to character- 

 istic West Ameri<;an mainland forms.
