Not illustrated. 1895 Excerpt:...specimens, females only, were taken from Procellaria capensis (locality?).

An adult male and two young taken on two specimens of Farallone Shag, Plialacrocorax dilophus albociliatus (Bay of Monterey, California), and one adult male from a California Brown Pelican, Pclccanus calif or nicus (Bay of Monterey, California). The pelicans and cormorants congregate in great numbers on the same rocks in Monterey Bay, and it is not surprising to find a straggling individual of this cormorant parasite on a pelican. Nitzsch's specimen was collected on a ffalieus carbo, and the specimen described by Nitzsch as gyroceros, but declared by Taschenberg t...
