referred, with some doubt, to the genus Mauisaurus of Dr. Hector, 

 founded upon a Saurian from the Cretaceous formation of New 

 Zeahiiid. He gave it the name of A/auisaurus Gardneri in honour 

 of its discoverer. A small heap of pebbles was found in the neigh- 

 bourhood of the ril)s ; and it was supposed that these had been con- 

 tained in the stomach of the animal.

Note on the Femoral BmsJies of the Mantidse. 

 B}- Prof. J. Wood-Mason. 



Since the abstract * of my pajicr on these structures and their use 

 was published, I have been enabled to consult M. Stal's memoir -f 

 entitled '' Orthoptera qutedam Afrieana ;" and I find that I have 

 been anticipated as to the discovery — the brushes, or rather the setu- 

 lose eminences which I call brushes, being thus described in a foot- 

 note to p. 3^2 of the work cited : — " In latere intcriore femorum 

 anticorum Mantoileonim adest apicem versus prope marginem infe- 

 riorem spatium parvum leviter convexum, oblongum, dense brevis- 

 simeque setulosum." M. Stal makes no suggestion as to the possible 

 use of the brushes to the insects ; but I have ascertained J that they 

 are exclusively used for keeping the eyes and ocelli in a functional 

 condition, and that they are present in the young when these quit 

 the egg. 



A fuU account of my observations and experiments on numerous 

 living specimens belonging to several genera (5't'7iirocfj?7ia?a, Pseudo- 

 mantis, UieroduJa, &c. ) will be given in my paper.

On the Development of the Antennce in the Pectiniconi Mantidae. 

 By Prof. J. Wood-AIasox. 



The author shows that, down to the last change of skin but one, 

 no diflerence is to be detected between the two sexes of Gongyliis 

 gongt/lodes, cither in the form or in the proportional length of the 

 antenna?, which in both male and female are identically the same 

 simple and setaceous structures, consisting of two distinct basilar 

 segments followed by a multitude of very short and ill-dctined 

 flagellar ones, but that shortly after this event these appendages 

 in the male begin to thicken throughout that portion of their 

 length which in the perfect insect is bipectiuated, so as eventually 

 to acquire a compressed spindle-shaped form ; that this thickening 

 is the outward manifestation of the growth going on beneath the
