420 Mr. H.J. Carter on the Relation of the Canal-System 



Family 47. Gelechiidae. 

 Genus 103. Exodomorpha, Walker. 

 137. Exodomorpha divisella. Walker. 

 Natal (eight examples). 



Family 48. Pterophoridae. 



Genus 104. Agdistes, Hubner. 



138. Agdistes pustulalis, Walker. 

 Natal. 



There are also in the Collection two species of Tortricites 

 and two Tineites which I have been unable to determine ; and 

 as at present I do not possess sufficient knowledge of the 

 groups to refer them to their proper positions, I cannot attempt 

 to name them. I have to thank Mr. F. Moore, of the Indian 

 Museum, for very kindly assisting me in determining some of 

 the more obscure genera of Pyralites and Geometries. 



LVI. — Relation of the Canal-System to the Tubulation in the 

 Eoraminifera, with reference to Dr. Dawson's 'Daivn of 

 Life: By H. J. Carter, F.E.S. &c. 



As an illustration of the relation of the canal-system to the 

 tubulation in Foraminifera in the so-called u Eozoon canadense" 

 Dr. Dawson repeats, in his book just published (the ' Dawn 

 of Life'), p. 43, a fac-simile of the woodcut which illustrates 

 his letter in ' Nature ' (vol. x. p. 103, June 1874), which illus- 

 tration had been previously published in the 'Annals & Mag. 

 Nat. Hist.' (vol. xiii. pi. xix. fig. 1, June 1874), and also 

 appeared about the same time in the ' Monthly Microscopical 

 Journal.' 



By this I infer that the woodcut (which, in the ' Dawn of 

 Life,' is stated to be " after Carpenter ") is the most convincing 

 representation that Dr. Dawson can adduce of the identity of 

 Foraminiferal structure with that of the so-called u Eozoon cana- 

 dense " in the Laurentian limestone ; for we find in the ' Dawn 

 of Life,' p. 204, the following paragraph : — 



" In the ' Annals of Natural History ' for June 1874, 

 Dr. Carpenter has given a crushing reply to some objections 

 raised in that Journal by Mr. Carter. He first shows, contrary 

 to the statement of Mr. Carter, that the fine nummuline tubu- 

 lation corresponds precisely in its direction with reference to
