around which is grouped other similar species. In this arrange- 

 ment, pattern of coloring takes high rank, and the groupings 

 indicate species which may have had a common ancestry. That 

 this classification is in many respects faulty cannot be denied, 

 but it appears on the whole to be better than that of the Messrs. 

 Adams. 



A number of beautifully illustrated monographs of Conus 

 have been published : 



Sowerby. Conchological Illustrations. 137 colored figures. 



Sowerby. Thesaurus Conclry riorum (and Supplement), vol. iii. 

 450 species ; the plates containing about 650 figures. 



Reeve. Conehologica Iconica (and Supplement). 337 species. 



Kiener. Coquilles Vivantes. 324 species, 111 plates. 



Weinkauff. In Kiister's Continuation of Martini and Chem- 

 nitz's Conchylien Cabinet (completed 1875). 411 species, 71 

 colored plates. 



Weinkauff s Catalogue of Conus, published in 1874, contains 

 the names of 352 species, distributed into 17 groups or sec- 

 tions : 



1. Marmorei (C. marmoreus. Linn.). 2. Literati (C. literatus, 

 Linn.). 3. Figulini (G. figulinus, Linn.). 4. Arenati (C. are- 

 natus, Hwass). 5. Mures (C. ?nws, Hwass). 6. Varii ^ C. varius^ 

 Linn.). 7. Ammirales ( C. ammiralis, Linn.). 8. Capitanei (C. 

 capitaneus^IjiiiTi.}. 9. Yirgines (C. virgo, Linn.). 10. Dauci 

 ( G. daucus, Hwass). 11. Magi ( C. magus, Linn.). 12. Achatini 

 (C. achatinus, ChemnA 13. Asperi (C. a*per, Lam.). 14. 

 Terebri ( C. terebra, Born). 15. Bulbi (C. bulbus, Reeve). 16. 

 Tulipae (C. tulipa, Linn.). 17. Texti (C. textile, Linn.). 



The Cones are very variable in some of their characters, such 

 as the tuberculation of the spire and body-whorl, strire, colors 

 and the pattern of coloring ; so that the synonymy is very ditli- 

 cult to arrange satisfactorily. A number of species have been 

 characterized since the date of the last-named publication, but 

 on the other hand several species considered distinct by Dr. 

 WcMiikauff I have been obliged to consolidate, so that in the 

 following pages, arranged mainly in accordance with his cata- 

 logue, the number of admitted species will not be found to vary 

 materially from his enumeration.
