420 Bihliographical Notices, 



volume, which includes 592 species — no less than 2S9 being new, 

 with 30 new genera. With the species enumerated in Vol. I. the 

 total number of Heteroptera recorded in the ' Biologia ' is 1715, 

 rather more than half of which have been treated as new. 



Mr. Champion's work is not only faunistic, it is much more. The 

 descriptions are excellent, and there is scarcely one among the nine- 

 teen families dealt with, not excei)ting the Aradidaj and Anthocorida?, 

 in which the author has not succeeded in finding new, hitherto 

 overlooked characters for distinguishing the species. The sexual 

 characters are carefully noted, and in nearly every genus in more 

 than one of the species. The enumeration of the latter is in most 

 cases preceded by a synoptical table, much facilitating their deter- 

 mination. 



Mr. Champion is to be congratulated on having so successfully 

 cnrapleted this woik. the most important contribution to Hemiptero- 

 logical literature published during the last few years.

Gephyrocrinus Grimaldii, Crim'ide nouveau provenant des campagnes 

 de la '■Princesse Alice.' By R. Koehler and F. A. Bather. 

 Mem, Soc. Zool. France, xv. pp. 68-79, 4 text-figures. July 

 1902. 



The specimen herein described was dredged by the Prince of 

 Monaco at a dejith of 1786 metres near Hierro in the Canaries, and 

 not, as the authors state, " dans les parages des Aoores." It is 

 referred to the Hyoerinidte, a family represented until recently by 

 a single species, Hyocrinus BetJicIlianus, dredged by the 'Challenger.' 

 A second species, not yet described, was found by the ' Valdivia ' 

 near Endcrby Land, in the Antarctic. The present specimen is 

 therefore of great interest, all the more so since it is considered to 

 form the type of a new genus difteriug from Hyocrimis^ and, indeed, 

 from all known crinoids, in the fact that the food-grooves are carried 

 across from the fourth brachials to the orals on a thin unplatcd 

 membrane stretching like the web of a duck's foot between each 

 arm and the tegmen. The name Geplujrocrinus is suggested by 

 this resemblance to a suspension bridge. Minor points of distinc- 

 tion from Hi/ocrinus are the fusion of the basals, the greater thickness 

 of the cup-plates, the almost complete atrophy of the ambulacrals, 

 and the form of the pinnules, which have not the peculiar arrange- 

 ment characteristic of Hyocrhms. These diflPerences have induced 

 the authors to give a fresh diagnosis of the Hyocrinidae, differing 

 considerably from that in the ' Challenger ' Report. 



Although the unique specimen of G. Grimcddn is small, some- 

 what imperfect, and naturally cannot be sacrificed for minute 

 dissection, it has been found possible to give a very exact description 

 of all the details of its external anatomy. These have suggested to 

 one of the authors a renewed investigation of the type of Hi/ocrinus 

 BetJiellianus, with results that may be published more fully else- 

 where.
