76 Bihliographical Notices. 



creatures conf nins examples of all the p;roups of Metazoa which infest 

 land animals, except the Acanthocephala, and practicall}' of all those, 

 with the exception of tlie Crustacea, which are to be found in or on 

 marine creatures. As, however, Mr. Stcbhing records several species 

 of parasitic crustaceans in an article in the same part of the 

 publication, this group mig:ht bo added to Mr, Shipley's list. Besides 

 a tick, which has not been identified, there are two Trematodes, seven 

 Cestodes, six Nematodes, one Xematoraorph, and a Linguatulid. 

 Of these, six Cestodes, one Nematode, the Gonlins, and the Lingua- 

 tulid are new. The Cestode collection is not only rich in new species 

 but reveals as many as three new genera. Of the ten parasitic 

 species among the Crustacea in Mr. Stebbing's paper, six are new ; 

 aud there are four new genera. 



Mr. Shipley's article is followed by one by Mr. R. C. Punnctt on 

 the Xeraertincs. Out of twelve species, ^[r. I'unnett finds six 

 certainly new, while others are probably so. In the third memoir, 

 Mr. L. A. J3orradaile describes the larv.-e of the Robber-Crab (Birgus 

 latro). It was thought that the young of this curious and aberrant 

 land hermit-crab were born resembling the parent. J)r. Willey, 

 however, discovered that the females go down to the sea at the 

 breeding-season, and there wash otf their young, which are born as 

 zoccas. into the water. He succeeded in obtaining some of these 

 larviE, and Mr. Borradaile, after describing them iu some detail, comes 

 to the conclusion " that their characteristics are those of the Anoma- 

 lous Macrurain general, and of the Pagurineain particular .... and 

 that their special feature is .... a certain simplicity of form 

 throughout the whole organism." 



In the course of a memoir on the anatomy of the rare imperforate 

 Madrepore Neohelia porcellana. Miss E. M. Pratt notices the 

 following important features: — 1. A horny membrane lines the 

 hollow tube which forms the colony. 2. There are certain aper- 

 tures in the wall of the tube. 3. An epithelial layer and an 

 endodermal ring canal encircle each aperture, the latter communi- 

 cating with the ccelentera of the polyps. 



Previously known specimens of the species had all the form of an 

 incrustation on a Gorgonid stem. Miss Pratt appears to believe that 

 Dr. Willey's specimens had never any such support, but she is not 

 convincing on this points It seems possible that the apertures she 

 mentions were formerly occupied by branches of a Gorgonid or by 

 some adherent organism which subsequently fell off. She regards 

 Neohelia as being most closely related to Dihlasus. 



Mr, Boulenger describes, in a short note, a new blind-snake from 

 Lifu — the second species only of land-snake recorded from that 

 locality. 



Finally, Mr. Stebbing closes the vohmie with a long and careful 

 account, already alluded to, of certain groups of Crustacea. He, 

 records forty-six species of thirty-four genera. Eight of the genera 

 and twenty -three of the species are new. The most interesting form 

 is the new Koleohpas Willeyi, a soft-mantled cirripcde found living 

 in symbiosis with a hermit-crab.
