GEORGE GORMAN (Department of Biology, University of California, Los 
Angeles, California 90024) and collaborators have recently completed a 
number of studies in diverse areas of anolology: 
l. New karyotypes. Gorman has collected on Mona, Redonda and 
Blanquilla islands material of three Anolis which had not been previously 
karyotyped. He is reporting on these with Brad Stamm who did the actual 
chromosome preparations. The most interesting result is for the Mona 
anole, A. monensis. Though it has sometimes been regarded as a subspecies 
of A. cristatellus, its karyotype resembles in detail that of A. cooki, 
the arid area sibling of cristatellus. A. nubilus of Redonda has a 
karyotype identical to that of neighboring members of the bimaculatus group. 
Chromosomes thus confirm its membership in the group but add no new infor- 
mation. A. blanquillanus of Blanquilla has a 2n=36 karyotype and this fits 
as it should in the roquet group with which it had been placed on external 
characters, 
Gorman utilized the opportunity of the collecting visits to study the 
natural history of the three species, 
These are most detailed for the structural habitat of monensis and the 
behavior of blanquillanus. A. nubilus was not abundant. 
Despite the fact that it is a "solitary" anole, Gorman found no evidence 
of ecological release in A. monensis - "a typical trunk-ground lizard that 
does not seem to choose a broader variety of perch types than cristatellus, 
There is also no evident thermal niche expansion," 
The behavior of A. blanquillanus fitted its geographic and postulated 
phyletic position: intermediate between luciae of St. Lucia and bonairensis. 
The greater resemblance was to bonairensis: much tail-lashing before 
bobbing, few pauses in any display sequence, shorter total time for a 
display sequence and more peaks in a bobbing series. However, there was 
resemblance to luciae in a greater tendency to pause than in bonairensis 
and in the occasional partial retraction of the dewlap during the pause. 
2. A new interpretation of the roquet group. With Michael Soulé, 
Gorman, using new information from m electrophoresis, scoring 26 genetic 
loci, has reinterpreted the relationships and colonization sequence in 
the roquet group. The new data emphasize the distinctness of griseus and 
richardi, formerly considered conspecific. A. luciae is markedly distinct 
from other species and has strong similarities only to A. bonairensis and 
A. blanquillanus. The relative lack of similarity of luciae to griseus 
and trinitatis on St. Vincent and the relative similarity of these two to 
each other has brought Gorman and Soulé to the view that the former 
hypothesis that griseus and trinitatis are separate invasions of a luciae 
stock into St. Vincent is wrong and that griseus and trinitatis differenti- 
ated on the St. Vincent bank from a single invasion from the south. (As
