In the field and in the literature frequent mention is made of the occurrence of priceite in California. In the course of an investigation of the borax deposits of the Mohave Desert Region by the writer all the reported localities were visited. Invariably the priceite proved to be the calcium silicoborate, howlite. At the mines the howlite is generally referred to as pandermite (= priceite). True priceite, not hitherto reported, was found during this investigation at a small prospect in the Furnace Creek Wash in Inyo County, about two miles below the mill of the Pacific Coast Borax Company.
