82 Capt. F. W. Hutton on Peripatus novce-zealandice. 



originals* ; and as I have been working with a microscope for 

 nearly fifteen years it is not likely that I should publish any 

 facts which I had not taken the trouble to verify. 



After all, the difference between us on this point seems to 

 be owing to one or the other having turned the ovary inside 

 out. I state in my paper that the ova are developed on the 

 interior of the ovary, and that the testes (probably the same 

 as the masses of spermatozoa of Mr. Moseley) lie below it, 

 outside, but quite separated from it. Mr. Moseley in his 

 paper (which, thanks to the kindness of Mr. Travers, 1 have 

 been able to see) says that the masses of spermatozoa are 

 inside the ovary, while the ova are developed in sacs "hanging 

 from the margin of the ovary," and that he has found sperma- 

 tozoa " amongst the ovisacs on the exterior of the ovary " 

 (p. 768). I leave it to him to explain these curious facts. 



Mr. Moseley says that my figures are " most crude and 

 imperfect." This I allow ; for I have not the advantage of 

 being able to employ a professional artist, or even of correcting 

 proofs. But I maintain that they are accurate, which cannot 

 be said of all of Mr. Moseley's. For example, in pi. Ixxv. figs. 

 7, 8, and 10, the eyes are placed on the side of the head half- 

 way between the mouth and the antennce ; whereas they are 

 really situated on the top of tlie head, at the base of the 

 antennai, as shown in my plate, fig. 6. I will not be so rude 

 as to say that Mr. Moseley "must have been entirely deceived 

 in imagining he saw " them in that position ; but I think that 

 he has allowed his theory to run away with him. 



I do not see why " cross fertilization would never occur," if 

 there are males ; but even if it were so, we ought not to let a 

 theory interfere with our observation of facts. 



I quite understand the importance of determining tlie exis- 

 tence of foot-jaws in Peripatus, if such exist; but I think it 

 more important to state the facts exactly as they appear to 

 me. 



But there are other points of difference between us which 

 Mr. Moseley has not mentioned, which, if not of such high 

 theoretical interest, are still important as tests of accuracy of 

 observation. For instance, I say (p. 366) that the ovary is 

 placed above the stomach, while Mr. Moseley says (p. 766) 

 that it lies "below that viscus." Again, Mr. Moseley's trachese 

 are evidently the equivalents of my spiral fibres. Now both 

 these points can be easily tested by the examination of speci- 

 mens preserved in alcohol ; for the supposed trachea? will be 

 found in abundance on the lower portion of the oviducts.
