the fact that in the pectoral girdle the precoracoid is entirely 
excluded from the glenoid cavity, the whole girdle being very 
like that of Gorgonopsids, and the plate-like pelvis. The 
Russian type Deuterosaurus is a Tapinocephaloid. The Titano- 
suchids seem to agree in general features with the Tapino- 
cephaloids and Rhopladon belongs to the ‘“ family.” 
The fact that whilst in the skull Deinocephalia agree with the 
American Pelycosaurs, whilst in the post-cranial skeleton they 
resemble South African Therapsids, shows that the American 
forms must be included in the same great group, super-order, as 
the South African mammal-like reptiles. 
The conditions of the Therapsid middle ear are discussed in the 
paper. 
Dr. R. C. L. Perkins, M.A., F.Z.S., sent a paper dealing with 
the species of the genus Paralastor and some other Hymenoptera 
of the family Eumenide. All the described species are enume- 
rated therein, together with the descriptions of many new forms. 
Mr. Grorct JENNISON contributed some notes on colour- 
development in the Indian Wood-Stork (Pseudotantalus leuco- 
cephalus). 
A paper received from Dr. Pu. Lrurs, and communicated by 
Dr. G. A. Bounencer, F.R.S., F.Z.8., contained the description 
of a new Lizard from the Canary Islands, recently discovered by 
Dr. Cesar Boettger on Hierro :— 
LACERTA CHSARIS, Sp. n. 
Closely related to LZ. galloti D. & B., but size much smaller 
(66 to 77 mm. from snout to vent) and pattern of coloration 
more primitive from a phyletic point of view, a light vertebral 
streak being present in both sexes. 90 to 110 scales across the 
middle of the body; ventral shields in 10 or 12 longitudinal 
series; rostral usually touching the nostril; occipital broader 
than long.
