226 PROCEEDINGS OF THE \\Tlo\M. MUSEUM. vol. 38. 



outer lips nearly straight; ground-color yellowish white covered with 

 a thin smooth yellowish periostracum; pattern of fluctuating longi- 

 tudinal streaks of yellowish brown, which by their zigzag direction 

 and anastomosis leave roughly triangular patches of white of small 

 size all over the shell, except in the middle, where a tendency to the 

 usual paler girdle is manifest; near the canal there are about sixteen 

 paired prominent spiral threads, the intervals between the pairs 

 being more or less channeled; sutural sinus and canal rather deep. 

 Beighl of shell 41; of shoulder 35; maximum diameter of shell 15; 

 of canal 5 mm. 



There are a few small brown spots along the shoulder keel. Though 

 the pattern of coloration is different, the aspect of the shell recalls 

 the Antillean C. deles s ertianus . If the white triangles were bounded 

 by a definite dark line, this shell would approximate the pattern of 

 the Textile group. As it is, it is somewhat unique in character. 



Typt . -Cat. No. 123085, U.S.N.M. 



CONUS DALLI Stearns, 1873. 



Cape St. Lucas to Panama. 

 This very handsome cone is the only representative of the typical 

 Textile group on the coast of America, so far as known. 



CONUS LUCIDUS Mawe, 1828. 



Magdalena Bay, Lower California to the Galapagos Islands. 

 This seems to be a rare and very distinct species. 



CONUS SIEBOLDII? Reeve, 1848. 



Japan, according to Reeve. OfT the Galapagos Islands in 300 

 fathoms, U. S. Bureau of Fisheries steamer Albatross. 

 The specimen dredged by the Albatross had lost its spire and part 

 of the last whorl, but what was left seemed to agree very well with 

 Reeve's figure of sieboldii. 



CONUS PYRIFORMIS Reeve, 1843. 



West coast of Nicaragua and south to Panama and the 

 ( ialapagos Islands. 



This snow-white or pinkish pear-shaped cone can not be confounded 

 with any other. Hinds in 1843 named the young of this species | 

 C. patricius. 



CONUS CONCOLOR Sowerby, 1834. 



Acapulco, Stearns collection. 

 The specimen referred to agrees extremely well with Sowerby's 

 original figure in the Conchological Illustrations, hut not with the 

 figure given by Reeve in the leoniea. Sowerby gives no description 

 or locality, but refers in his list to the Proceedings of the Zoological 

 Society of London for 1841. Nothing was published in the Proceed- 

 ings for that year or any adjacent year in regard to this species. 

 Reeve's shell, which doe- no! agree with Sowerby's, is reported to 

 have come from China. Another figured in the Thesaurus is alleged 

 to be from India.
