24 THE NAUTILUS. 



Acmcea asmi was numerous on Chlorostomas. A. mitra Esch. and 

 A. rosacea Cpr. were found on the sandy beaches. 



Monoceros lapilloides Conr., are quite abundant in the crevices of 

 rocks constantly washed by the tide, and in the same localities a few 

 M. engonatum Conr. Here also in the roaming breakers were large 

 quantities of Purpura saxicola Val. There seem to be three well 

 defined varieties, white with many large varices, almost black with 

 small varices, and smooth with bands of brown. Among the rocks 

 and in little pools of water were large quantities of Chlorostoma fune- 

 brale A. Ad. They seem to be of two varieties, one plain and smooth 

 and the other with a crinkled band around the body-whorl. The 

 latter most abundant and largest in size. Chlorostoma brunneum 

 Phil., is in the same locality but not nearly so numerous. Many of 

 the C. brunneum are dead shells inhabited by the hermit crabs. In 

 the same pools were Calliostoma costatum Mart, but numbers of them 

 dead and the hermit crab in possession of the premises. A few C. 

 canalicnlatum Mart, and C. annulatum, were also found but they 

 were not such fine shells, as those washed upon the shore by the 

 storms of winter. Low down on the rocks in the roaring waves were 

 found some Haliotis cracherodii and some fine sea urchins. With the 

 Haliotis we found a large beautiful Rupellaria lamellifera Conr. 

 The mussels are very abundant in some places, literally darkening 

 the rock. I think I found four species ; Modiola modiolus L., M. 

 recta, Mytilus edulis and M. californianus Conr. Crepidula adunca 

 Sby., was very abundant on the shells of Chlorostoma and C. navi- 

 celloides Nutt. in the apertures of dead shells. I found a number of 

 Chitons but have not yet been able to classify them. 



On the beaches I found many species of shells that I have never 

 found alive, Olivella biplicata Sby., Conus calij 'ornianw Hds., Nassa 

 mendica Old., Amphissa corrugata Rve., Astyris gausapata Gld., 

 Marginellajewettii Cpr., Lacuna unifasciata Cpr., Bittium quadrifila- 

 tum Gld., and many others. 



On the large beach at Monterey I found many rocks containing 

 dead shells of borers, Parapholas californica and Pholadidea penita. 

 In deep quiet pools at Point Pinas I found beautiful starfish. Some 

 of a deep orange color, others dark red, some dark purple, others 

 pale yellow. I saw some beautiful Anemones differing from any I 

 had seen, they were eight or ten inches in diameter, and beautifully 

 iridescent, the play of colors resembling a great opal with greenish 

 lights. The holidays ended, and reluctantly I said good-bye to the 

 beautiful bay.
