Identification Possibly Johnson (1897) combined two species in his description. According to Salazar-Silva (2006:149) the specimen redescribed by Ruff (1995), which he thought was the holotype, was one of two syntypes (but according to LACM curator Leslie Harris there are three specimens). According to Salazar-Silva there is a specimen at MCZ which she thinks is the one Johnson described. She gives the details as "MCZ 135, San Pedro, California, collected H.P. Johnson, 25 July 1895, No 433". She does not explain how this specimen got to MCZ, when Johnson states his specimens are deposited at the University of California, where he was a professor. [details]
