the occurrence of two eyes, though in some cases with a high 

 power the apparently simple eye could be resolved into two, but 

 it was very unusual in Syncheeta. There were, he thought, 

 some reasons for suggesting whether this specimen was 

 mature. 



Mr. Western said it was undoubtedly mature, because it 

 contained eggs, and also the eye-spot. 



The thanks of the meeting were voted to Mr. Western and 

 to Mr. Hood for this communication. 



Mr. E,. T. Lewis said it would, no doubt, be remembered that 

 at the meeting of the Club in January, 1892, he read a short 

 paper " On a Species of Ixodes found upon a South African 

 Ijizard." This paper was printed in the last number of the 

 Journal, and illustrated by a plate. Having by request sent to 

 Mr. Michael a reprint, in which the figure was coloured, he had 

 been struck by its resemblance to one described by Lucas at the 

 seance of the Entomological Society of France, in July, 1845, 

 and published in the annals of that Society, with a coloured 

 plate. Lucas's specimens were found upon a python imported 

 from Senegal to the Zoological Gardens in Paris, and on read- 

 ing the descriptions and comparing the measurements with 

 those of the specimens from the lizard he came to the con- 

 clusion that the two were probably of the same species, or, if 

 not, they were very closely allied. The chief diiference 

 appeared to be in the shape of the markings on the dorsal 

 surface, which seemed a little too symmetrical to be quite 

 natural. He had mentioned in his paper that there were some 

 specimens at the British Museum which were unnamed, and in 

 the absence of any other name it was proposed to call the 

 species Ixodes Varani, after the Varanus Lizard, upon which 

 his specimens had been found. If, however, they were really 

 identical with those described by Lucas, the name given by 

 him, Ixodes Flavomaculatus, must be substituted. Mr. Lewis 

 also called attention to a slide exhibited under a microscope in 

 the room, containing some objects which had been sent to him 

 under the impression that they were animal parasites. They 

 had been found upon the new Marsupial Mole, Notoryctes 

 typhlops, discovered by Mr. Coulthard in 1888 at Idracowra, in 

 Central Australia, and subsequently described and figured by 

 Dr. Stirling in the proceedings of the Royal Society of
