Major Yerbury in Western India in 1886—1887, forming a continuation 

 and completion of two previous papers by Mr. A. G. Butler on Lepidoptera 

 collected by the same gentleman in similar localities. The present collection 

 contained examples of over 200 species of Heterocera, of which about one 

 fourth were described as new. Mr. Warren remarked upon the abnormal 

 development of separate organs, such as the antennae and palpi, in tropical 

 insects, as being rather specific aberrations from a generic type, than as 

 warranting the erection of new genera. — A communication was read from 

 Mr. Martin Jacoby, containing descriptions of some new species of Phy- 

 tophagous Coleoptera from Kiukiang, China. — Mr. F. E. Beddard read 

 some notes on the structure of a peculiar sternal gland found in Didelphys 

 dimidiata. — Mr. G. A. B oui eng er read a paper on the scaling of the 

 reproduced tail in Lizards, and pointed out that the scaling of the renewed 

 tails of Lizards may, in some cases, afford a clue to the affinities of genera 

 or species to one another. — Mr. F. E. Beddard gave a preliminary notice 

 of an apparently new form of Gregarine, found parasitic on an earthworm of 

 the genus Perichaeta from New Zealand. — P. L, Sclater, Secretary,

25*'' April, 1888. — 1) On additional Evidence of the Genus Ichthyo- 

 saurus in the Mesozoic Rocks (,, Rolling Downs Formation") of N. E. 

 Australia. By R. Etheridge, Junr. Since Prof. McCoy announced the 

 discovery of Enaliosaurian Reptiles in Australia some years ago, little has 

 been done towards the further elucidation of their history and structure. In 

 this paper the author describes the fore part of the skull of an individual 

 found on Marathon Station, Queensland, to which the name oi Ichthyosaurus 

 Marathonensis is applied ; and he compares it with 7. atistralis, McCoy, the 

 only other Australian species yet described, as well as with European forms. 



The specimen was obligingly communicated by Mr. C. W. de Vis. 2) On 



additional Evidence of the Occurrence of Plesiosaurus in the Mesozoic Rocks 

 of Queensland. By R. Etheridge, Junr. The Plesiosaurian remains 

 described in this paper are from the ,, Rolling Downs Formation" (Creta- 

 ceous) of the Walsh River, North Queensland, and were kindly communi- 

 cated to the author by Mr. C. de Vis, Curator of the Queensland Museum, 

 Brisbane. From a mass of impure earthy limestone at least four vertebrae, 

 and fragments of ribs have been worked out, which are believed to be those 

 of the dorsal series of a Plesiosaurus. These vertebrae cannot be identified 

 ■with either of the two Australian species of Plesiosaurus., nor with any of 

 those known to occur in the Mesozoic rocks of New Zealand. — 3) Notes 

 on the Nidification of Rhipidura Preissi, Cabanis, and Malurus pulcherrimus , 

 Gould. By A. J. North, F.L.S. The two species of birds, whose nests and 

 eggs are here described, were found breeding in the neighbourhood of Derby, 

 N.W. Australia, by Mr. Froggatt during 1887— 1888. — 4) Notes on some 

 Ophidia from the vicinity of King's Sound, N.W. Australia. By William 

 Macleay, F.L.S. , &c. The Snakes collected about King's Sound by Mr. 

 Froggatt, were of six species : four of these previously described are Nardoa 

 Gilberti, Gray ; Brachysoma simile, Macleay ; Pseudechis Darwiniensis, Macleay ; 

 and a very young specimen of Acanthophis antarctica , Wagler. The new 

 species described are Dipsas ornata, and Dicmenia angusticeps. — 5) Descrip- 

 tion of a new Tripterygium from Port Jackson. By E. P. Ramsay, L.L.D.,
