122 THE NAUTILUS. 



Olivn porphyria, ACi^m?, found only a broken fragment. I liunttrd 

 in vain lor even tl'at. I doubt it Panama is now its natural habitat, 

 as the shell was scarce in IhiJU and is not lound there now. Adams 

 took 1500 Nassa punaniensis on the reef that juts out from the old 

 sea wall. Kot a single Nassa is to be found there now. Of Nassa 

 hileosfoma, Adams took 3iiO near the oh) sea wall. They are not to 

 be found there now, they having migrated two miles across the bay 

 where a bushel could be taken at one tide. Adams found fourteen 

 species of Nassa, I found four. Adams found incredible numbers of 

 Neriia, two species, took 3200 specimens. Of these only 400 were 

 Nerita scabricosta, the only species to be found in considerable num- 

 bers now on the high-tide locks. Adams found 29 species of Col- 

 umbella, 3000 specimens ! ! Four good specimens of C. harpac' 

 form's, brought u[) by hermit crabs, and halt a dozen other species, 

 beach worn, rewarded persistent search. 



Monoceros cinynlatiim. Adams lound only 75, most of them 

 young. Of these one may get a thousand adults in one tide — but 

 not at Panama, at Taboga Island. Adams took 3900 specimens of 

 Lilorina, 12 species. Now, only one species to be found in consid- 

 erable numbers. Adams found 110 specimens ot Ricinula reevtana, 

 I found one. 



Conus, then and now : hmnnevs, 4 — ; gladiator, 70 — 1 ; ma- 

 hoyani, 17 — 0; nux, 2 — 12; princeps, 8 — 4; purpurascens, 12 — 1 ; 

 regularis, 1 — 0; im(s, — 2.5. I was fortunate enough to find two 

 specimens of Cunns pannicidus Lam. at Taboga, one alive, and both 

 splendid specimens. Has this or any other of the Texti been re- 

 corded from the Panama Province? A fine specimen of Conus 

 fergusimi Shy. was found, a species not recorded in the Conch. 

 Iconica, and considered doubtful by Tryon. This specimen, after 

 removal of the olive-green, persistent epidermis, shows perpendicular 

 stripes of delicate yellow alternating with lavender, from rounded 

 shoulder to base where the colors merge into pale ashy brown, colu- 

 mella and interior violaceous wliite. All oth^r specimens that I 

 liave seen are dead while. The figure in Tryon's manual is not C. 

 fergvsoni either in form or color. Fergusoni has the rounded 

 shoulder and heavy form of Conus betiilinns or C. gluucus, depressed 

 accuminated spire, whorls eight, rounded and canaliculate. 



Purpura seems to be more plentiful than whem Adams was there. 

 He found 8 species, GOO specimens. Two miles from Panama one
