Abstract
SEVERAL papers recording new work have been published recently in the Transactions of the San Diego Society of Natural History. Vol. 8 (Nos. 6,7,8,9), March 1935, contains a paper on new marine mollusca of West Mexico by Herbert N. Lowe, a description of a new trilobite from Northern California by Harry E. Wheeler, a revision of some Californian Astrodapsis by George L. Richards and some new species of molluscs of the genus Triphora by Fred Baker and V. D. P. Spicer. Both the mollusc papers deal with the shells alone, but there is in the first a good annotated list of shells collected at Punta Penasco, Sonora, Mexico. The trilobites include a very well preserved specimen of a new Griffithides from the Permian Nosoni formation, its nearest known relative being G. acanthiceps from the Carboniferous limestone of England. A second paper by the same author discusses and re-describes the original type specimen of Vogdes Phillipsia (Griffithides) ornatus from the Lower Coal measures, Conway County,Arkansas, renaming it Griffithides conwayensis.
