80 THE ZOOLOGIST. 



Cerithium rupestre, and Nassa conspersa. Helix paupercula was said to 

 furnish the chief food of the Tarantula spider, Lycosa maderiana, and entire 

 shells of Helix phana had been found in the stomach of a Kestrel hawk 

 shot on one of the islands. The Petrels exhibited with their eggs were 

 Pelagodroma marina and Oceanodroma cryptoleucura, which were found 

 nesting in burrows, after the manner of the Shearwater, Puffinus kuhli, of 

 which great numbers were also breeding there. Mr. Howard Saunders 

 offered some critical remarks on these birds, referring chiefly to what was 

 known of their geographical distribution. 



Mr. George Murray exhibited full-grown complete specimens of some 

 giant Laminarians from the Pacific, Nereocystis, Egregia, and Macrocystis, 

 and some very fine specimens of Postelsia, collected by Mr. W. E. Shaw on 

 the coast of California. He made some remarks on the distribution of 

 Californian Laminariece, and illustrated some points in the structure of their 

 reproductive organs. 



A paper was then read by Prof. T. Eupert Jones and Mr. Frederick 

 Chapman on the relations of the Fistulose Poly morphines and the Ramulince, 

 with the view of showing the existing evidence for or against the suggestion 

 that several specimens referred to the latter of these two subfamilies may 

 really belong to the former. With this object the authors enumerated, 

 firstly, all the known examples of Polymorphince having fistulose, tubulose, 

 and racemose outgrowths, and, secondly, all the Ramulina known, whether 

 published or not, figures for comparison being supplied and supplemented 

 by lantern-slides. Sixty-nine figures of the former and forty-four types or 

 species of the latter were shown on the screen. The most interesting 

 feature in Ramulina was said to be the Polymorphine character of the 

 initial chambers in some good specimens of R. grimaldii and R. cervicornis, 

 and an approach to Polymorphine structure in the swollen bifurcations in 

 other species. Just as Milioline beginnings in Articulina, and Nodosarian in 

 Frondicularia, &c, do not deprive these of their independent standing as 

 genera among Foraminifera, so Ramulina is distinct from Polymorphina. 

 Other features and characters were also referred to, giving the genus a 

 substantial position among the hyaline or perforate Foraminifera. In some 

 respects this paper may be regarded as supplemental to the monograph on 

 Polymorphina by Messrs. Brady, Parker and Jones, Trans. Linn. Soc. 

 vol. xxvii. (1870).
