fore limbs are moditied into paddles. Two specimens have been 

 obtained. The extreme length of the skeleton of the larger is about 

 270 millim. ; and, with the exception of the abdominal ribs and 

 some parts of the pelvic girdle, it is perfect. The author described 

 minutely the various parts of the skeleton, concluding with some 

 remarks on the affinities of the Crocodiles with the Plesiosaurs. 

 Neustkosauras indicates that tlie latter had ancestors which were 

 terrestrial in habit. 



BIBLIOGRAPHICAL NOTICE. 



Aid to the Identification of Ins/'cfs. Edited by Charles Owen 

 Waterhouse. Lithographs by Edwin Wilson. London : E. 

 W. Janson. 



The first volume of this work, to the earlier numbers of which we 

 called attention last year in the March numl^er of the ' Annals,' is 

 now complete. Of the KM) plates, S5 have been taken from the type 

 specimens, lent for the purpose by their possessors, of whom a list 

 is given. Mr. Watei'house has also supplied short notes on many 

 of the species, and two indexes, the one systematic and the other 

 alphabetical. With few exceptions, the insects figured are remark- 

 able either for their beauty or for their peculiar form and structure. 

 One of the most singular is Apodi'vun ieiniissimus, with a neck more 

 than double the length of its body. Plectof/aster pectinicornis and 

 Cycloj'teplus ci/aneiis are two curious longicorns. The Neuroptera 

 are admirably figured ; but bj' omitting the legs the effect of the 

 handsome Asc(d<iphi>s- Ramhurii is considerably impaired. Com- 

 pare this with Ilelcoptcri/.v rliodiogramma^ and the difference is 

 obvious. The Lepidoptera, represented in twenty-nine plates, are 

 not so striking (considering the marvellous beauty of some of the 

 order) as might be expected. One, however, with its enormously 

 long-tailed hind wings {Endn'monia argipliontes) is an exception. 

 Diptera and Orthoptera have each one representative ; both orders, 

 especially the latter, abound in remarkable forms. In the next 

 volume we shall be glad to see some of them represented by so 

 excellent an artist as Mr. AVilson.

Charles Darwin. 



In the face of the many and often admirable oulogia of Charles 

 Darwin that have appeared in nearly all languages during the last 

 few days, we feel that to add to their number is in some degree a 

 work of supererogation : but we cannot refrain from offering our 

 tribute of I'espect to the memory of tlie illustrious naturalist who
