THE NAUTILUS. 9 
ORANGE, CALIFORNIA. 
[Excerpts from report of Mrs. M. F. Bradshaw]. 
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: IJschnochiton conspicuus, 
Mopalia muscosa, Trachydermon dentiens, T. hartwegii, Lepidopleurus 
rugatus, Cumingia californica, Lucina californica, Diplodonta or- 
bella, Chlorostoma fusescens, C. gallina, C. aureotinctum, Volvaria 
varia, Parapholas californica, Pholadidea penita, Nettastomella dar- 
winti, Norrisia norrisi, Leptothyra baeula, Phasianella compta var. 
pulloides, Mytilus bifurcatus, Septifer bifurcatus, Laswea rubra, Chama 
pellucida, Fissurella voleano, Adula falcata, Lithophagus plumula, 
Astyris gausipata, Cerostoma nuttalli, Conus californicus, Corbula 
luteola, Hipponyx antiquatus, Macron lividus, Monoceras lapilloides, 
Milneria minima. 
Went to day (February 14), to Fisherman’s Bay, and were at 
last successful in finding the Semele 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 bimaculatus, Trivia 
californica, and nearer to shore in the weeds on the rocks one live 
Chama muricata. 
GENERAL NOTES. 
Nore 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 ‘‘ Mahé” by Valenciennes. This must 
be Mahé 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
