It is early, of course, to lay down any general statements ; and 

 were it not that Mr. Perkins has collected so many species and in 

 most cases so many individuals of each species, I should have 

 contented myself with a plain description of fact and should not 

 liave ventured a\>on comment. It may be permissible, however, 

 to indicate the " Oriental " facies of the fauna and the absence of 

 very peculiar types. The latter statement, in fact, appears to 

 hold good generally for oceanic islands, so far as our imperfect 

 data enable us to speak. It argues their really oceanic origin and 

 their short existence. Even in Kerguelen and Marion Is., which 

 are remote from traffic and can hardly have been stocked by human 

 means, the one known species, Acanthodrdus keiyuelarum, is only 

 specifically difierent from the Earthworms most nearly allied upon 

 the adjoining maiulands. And these islands are possibly among 

 the most ancient of oceanic islands. 



AllolobojjJiora fietida, 8av. 



Numerous examples of this widely distributed species from 

 Hulemanu, Kausi. 



Allohhopliora ccdiginosa, Sav. 

 Hub. Waiulua, Oahu.

There are a large number of examples of the variety " arhorea " 

 (smaller, and with tuberculapubertalis only upon xxix.& xxx.), which 

 llosa believes to be identical with Kinberg's "Hypogoeon havuicus." 

 Its occurrence, therefore, is not a new fact. 



Hah. Molokai, and Kawailoa lliver, Oahu. 



Fontoscolex hawaiensis, n. sp. 



Of this appuroully new spucius soiiio 8 or 10 examples were 

 collected. 



The length of a fair sized specimen is 142 mm ; the breadth at 

 the clitellum 4 mm., elsewhere rather less. The number of 

 segments is rather more than 210; after the 128th segment is 

 an oval swelling upon the body 3 mm. long and commencing about 

 90 mm. from the anterior end ; this is the structure wliich has 

 been described in other species, and regarded as a growing point. 

 This modified region of the body appears to be constant in position ; 

 this is shown by the following measurements of two individuals: — 



A. B. 

 Length of body in front of " growing region " . . . . 90 80 

 Length of body behind " growing region" 47 40 



The intestine proper appears to begin at the end of the clitellum ; 

 there is here a distinct circular valve, and the intestine has a 

 distinct typhlosole projecting into its lumen. The calibre, however, 

 is not greater.
