that *' the only object that any truly sincere observer can have is to 

 establish the truth." 



Since I left the sea-shore I have made extremely few carcino- 

 logical observations. Our freshwater crustaceans are not numerous. 

 There are a few crabs, some prawns (Palceruon), among them a large 

 Macro!) rachium and a genus allied to Atya, and two species of 

 ^(jlea. One of the species of u.'Eglea is rather common in the 

 small rivers of the Serra (about 1000 metres above the level of 

 the sea) ; this species is very frequently infested by that curious 

 parasitical worm Temnocephala, which Claude Gay discovered on 

 the crustaceans of Chili. 



I do not know whether you may be interested in any of the 

 objects to which I have devoted my time during the last ten years — 

 heterostyled and self -sterile plants, termites, honey-bees {Melipona 

 and Tri(joiia), butterflies, &c. Kx, present I am collecting and 

 observing the larvae of our caddis tlies, some of which construct 

 very curious cases, quite different from those of the European 

 species. 



Believe me, dear Sir, with sincere respect, 



Very faithfully yours,

To the Editors of the Annals and Magazine of Natural History. 



Gentlemen, — Will you, in reply to Mons, Giard's remark in the 

 September number of your magazine, that I have endeavoured to 

 prove that " the Nauplins described by Fritz Miiller as belonging 

 to Penceus cannot be the young of any prawn," permit me to 

 say that I have only attempted to show that, as far as our know- 

 ledge extends, it has not been proved to be so. 



I regret that I should have omitted doing justice to M. Giard's 

 communication on the embryogeny of the lihizocephala ; but I 

 regret to say that I had not previously seen the paper, neither does 

 it appear to have been noticed in the ' Zoological Record ' for 

 1874. 



Yours obediently, 



Oct. 16, 1878. C. Spence Bate. 



Amphi[ioda in Sponges. 

 By the Rev. T. R. R. Stebbing, M.A. 



In the interesting paper by Mr. H. J. Carter, F.R.S. ('Annals,' Aug. 

 1878), on the various creatures that find a home in sponges, certain 

 Amphipods are mentioned. The list of these may be enlarged. There 

 are two species which I have taken in sponges and in sponges only, 

 namely Exunguia stilipes (Norman), which is in all probability the 

 same as Cratippus tenuipes (Spence Bate), and Att/lus gibbosus 

 (Spence Bate). Of Leucothoii articidosa (Leach), which can often 

 be obtained by dredging, I once found several line specimens in a
