FAMILY OTITIDAE This is the family that until recently was called Ortalidae by authors, but, owing to the preoccupation of the generic name Ortalis in Ornithology, the name was changed to Otitidae. There are four genera of the family in the present collection, represented by five species. One of the species is widely distributed, being almost cosmopolitan, its saprophagous larval habits making it a ready subject for transportation in commercial vessels. All the others appear to be new to science, and possibly they are indigenous to Guam.
