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 Ilustrations. 137 colored figures. 
Sowerby. Thesaurus Conchyliorum (and Supplement), vol. iii. 
450 species ; the plates containing about 650 figures. 
Reeve. Conchologica Iconica (and Supplement). 337 species, 
Kiener. Coquilles Vivantes. 824 species, 111 plates. 
Weinkauff. In: Kiister’s Continuation of Martini and Chem- 
nitz’s Conchylien Cabinet (completed 1875). 411 species, 71 
colored plates. 
Weinkaufi’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.). 38. Figulini (C. figulinus, Linn.). 4. Arenati (C. are- 
natus, Hwass). 5. Mures (C.mus, Hwass). 6. Varii ( C. varius,” 
Linn.). 7. Ammirales (C. ammiralis, Linn.). 8. Capitanei (C. 
capitaneus, Linn.). 9. Virgines (C. virgo, Linn.). 10. Dauci 
(C.daucus, Hwass). 11. Magi(@. magus, Linn.). 12. Achatini- 
(C. achatinus, Chemn.). 13. Asperi (C. asper, Lam... 14. 
Terebri (C. terebra, Born). 15. Bulbi (C. bulbus, Reeve). 16. 
Tulip (C. tulipa, Linn.). 17. Texti (C. textile, Linn.). 
The Cones are very variaole in some of their characters, such 
as the tuberculation of the spire and body-whorl, striz., colors 
and the pattern of coloring; so that the synonymy is very difli- 
cult to arrange satisfactorily. A number of species have heen 
characterized since the date of the last-named publication, but 
on the other hand several species considered distinct by Dr. 
Weinkauff 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.
