[Introduction] The majority of the species recorded in this paper come from the coast of Mexico. With a few exceptions, which are specified in the text, the material was collected by Capt. F. E. Lewis during the cruises of his yacht ' Stranger ' in the years 1934 and 1937. He was assisted by Mr. W. Williams, of Pomona College, California, who was responsible for a large measure of the actual preserving and recording. A few specimens collected from points farther south and two from Haiti are included in the paper because, though not coming within the region specified in the title, they also were taken during the cruises of the ' Stranger ' and seem to be worthy of record. The material was kindly submitted to us for examination by Dr. C. E. MacGinitie, of the Kerckhoff Marine Laboratory, Corona Del Mar, California .. Very few of the forms now listed are comprised in the former collections from the region. This may be due to the fact that the previous collections were made for the most part in deeper waters than were those of the ' Stranger.' In the following complete list of the thirty-four species taken five, Sigalion lewisii, Eulepethus mexicanus, Onuphis zebra, Arenicola glasselli, and Clymene papillata are recorded as new to science ; and seven, Eupholoe philippinensis, Hesione intertexta, Nereis rava, Glycera lancadivae, Travisia arborifera, Dasychone picta, and Spirorbis militaria, appear to be new records for the west coast of North or Central America. The types of the new species are in the authors' collection, and co-types, when available, will be deposited in the British Museum.
