18 THE NAUTILUS. 



given to molluscan life in particular and an extremely interesting 

 collection was made of the different forms. 394 species were ob- 

 tained, a practically complete list of which follows. In addition to 

 the mollusks, four species of brachiopods were collected. 



The major part of the collecting was done along the shore about 

 Pacific Grove, especially at what is locally known as the " Third 

 Beach," and an interesting expanse of rocks called the " Big Tide 

 Pool." In addition to this, a number of dredging excursions were 

 undertaken with the aid of a gasoline launch, which resulted very 

 successfully. Most of the dredging was done in quite shallow water, 

 although one trip was made to a point off Moss Landing near the 

 middle of the bay. On this occasion we twice pulled up the dredge 

 filled to the brim with living echinoderms of the genus Echinarach- 

 nius, the common " sand-dollar," some two bushels in all. All of 

 the mollusca collected on such occasions were given over to the 

 writer, and his sincere thanks are due to Professor George Clinton 

 Price, in charge of the laboratory, to Mr. Frank A. Woodworth, of 

 Pacific Grove, and to many of his fellow-students for much valuable 

 aid in the way of numerous specimens, pertinent suggestions and 

 help of every description in the preparation of this paper. 



The writer is also greatly indebted to Dr. William H. Dall and 

 Mr. Paul Bartch, of the United States National Museum, who 

 kindly determined all doubtful material and who have now in hand 

 the description of the many new or undescribed species found. The 

 new species are marked with an asterisk. 



BRACHIOPODA. 



Glottidia albida Hinds. Several living specimens were obtained 

 at from twelve to forty fathoms' depth. 



Terebratulina caput- serpenlis Linne\ A few very young speci- 

 mens, presumably of this species, were dredged. Adult specimens 

 are occasionally brought in front deeper water by the fishermen, 

 usually attached to coral. They are of the form which used to be 

 known as var. unguicula Carpenter. 



Terebratulina transversa Dall. A few poor specimens were dredged 

 at various depths, adhering to fragments of hard blue clay, shells, etc. 



Laqueus californicus Koch. We obtained no good specimens of 

 this handsome brachiopod, but I saw numbers of fine ones which had 

 been brought in by the fishermen.
