hamata. The same author of late (1883) has published a short note, 1 in which he 

 mentions a species of the same genus Kochlorine, probably different from his Kochlorine 

 hcmata, and inhabiting cavities in a Haliotis shell from the Cape of Good Hope. For 

 this .second species the name of Kochlorine bihamata is proposed. 



The ( lirripedia of the North-American coast have been somewhat neglected by zoologists. 

 In the report upon the invertebrate animals of Vineyard Sound and the adjacent waters, 

 published (1873) by Prof. A. E. Verrill, 2 and in Dr. Spencer F. Baird's report for 1872, five 

 species of Balanus (Balanus amphitrite, Balanus eburneus, Balanus improvisus, Balanus 

 crenatus, and Balanus balanoides) ; Coronula diadema; four species of Lepas (Lep>as 

 anatifera, Lepas anserifera, Lepas pectinata, and Lepas fascicularis) ; and two species 

 of Conchoderma (Conchoderma auritum and Conchoderma virgatum) are enumerated. 



Macdonald 3 (1869) published a description of an "apparently new genus of minute 

 parasitic Cirripeds, between Lepas and Dichelaspis." The species is called Paradolepas 

 neptuni, and was found on the gills and respiratory appendages of Neptunus pelagic us, 

 one of the swimming crabs occurring in great plenty at Moreton Bay (Australia). The 

 species is, also, according to him, abundant at Sydney, and amongst the islands of the 

 south-western Pacific. I believe the genus Paradolepas to be synonymous with 

 Dichelaspis, Darwin. Macdonald met with another small pedunculate Cirriped in Nandi 

 Kay, Vanua Levu, Fiji, also parasitic upon a swimming crab, but he neglected to decide 

 whether this was identical with the other or not. 



F. W. Hutton 4 (1878) has published a list of the New Zealand Cirripedia in 

 the Otago Museum. The short notice contains an enumeration of eighteen species 

 of Cirripedia, the description of two new species of Elminius (Elminius sinuatus 

 and Elminius rugosus), and one new Pollicipes (Pollicipes darwinii), all three from 

 New Zealand. 



Fritz Midler 5 (1867) observed in Desterro, southern Brazil, a new species of 

 Balanus (Balanus armatus). The species Hves in sponges, and is distinguished by 

 a rich and very peculiar armature of its cirri. The commonest species of Balanus 

 occurring in the same locality is Balanus improvisus, var. assimilis, and the same author 

 describes a probable hybrid between this variety and his Balanus armatus. 



With regard to the Cirripedia inhabiting the skin of whales, we possess a paper from 

 W. H. Dall, 6 and a short note, published by Steenstrup as a footnote to Liitken's Mono-
