THE NAUTILUS. 

 ORANGE, CALIFORNIA. 



[Excerpts from report of Mrs. M. F. BradshawJ. 



To-day (February 13) we went to the blue rock above Laguna 

 and had great success, finding some species not before collected by 

 us. Digging in the soft rock with a hatchet and turning over loose 

 rocks brought us the following species : Ischnochiton conspiciius, 

 Mopalia muscoaa, Trachydermon dentiens, T. hartwegii, Lepidopleurus 

 rugatus, Camingia californiea, Liicina californica, Diplodonta or- 

 bella, Cklorostoma fasescens, C. gallina, C. aureotinctum, Volvaria 

 varia, Parapholas californica, Pholadidea penita, Nettastomella dar- 

 winii, Norrisia norrisi, Leptothyra bacula, Phasianella compta var. 

 pulloides, Mytilus bifurcatus, Septifer bifurcatus, Lastea rubra,Chama 

 pellucida, Fissurella volcano, Adula falcata, Lithophagus plumula, 

 Astyris gausipata, Cerostoma nuttalli, Conus californicus, Corbula 

 luteola, Hlpponyx antiquatus, Macron lividus, Monoceras lapilloides, 

 Milneria minima. 



Went to day (February 14), to Fisherman's Bay, and were at 

 last successful in finding the Setnele rupium. Down deep in the 

 sand where they were built upon themselves two or three stories 

 high, down cellar under water, here hide the beautiful Semele. The 

 incoming waves kept us from looking long or carefully, which was 

 greatly to be regretted, as it is a long walk to this place and only to 

 be approached at the very lowest tide; even then one is continually 

 obliged to run from the waves, so that it will never be possible to get 

 many. We also found a few Diplodonta orbella, Kellia suborbic- 

 ularis, Rupellaria lamellifera, Megatebennus bimacalatus, Trivia 

 californica, and nearer to shore in the weeds on the rocks one live 

 Chama muricata. 



GENERAL NOTES. 



NOTE ON MARIAELLA DUSSUMIERI. It is tolerably evident that 

 we have all along been making a stupid blunder about the type lo- 

 cality of this slug. The original specimen, in the British Museum, 

 is labelled simply as from " Mahe " by Valenciennes. This must 

 be Mahe the French colony on the southeast coast of India, not far 

 from the Travancore Hills, whence came Mariaella beddomei (G.- 

 Aust.), which is, to all appearances, the same animal. I had been
