The zygomatic arch differs considerably, the maxillary processes being broader and standing out at a greater angle; the squamosal process appears rather slighter, but is more horizontal, not drooping so much as in the type species ; it will therefore be seen that the " greatest breadth " given of the skulls is the same in both species, though the width across the brain-case is much less in the species now being described. The mandibles are decidedly smaller, with very small and almost round condylar processes, whereas these are large and oval in /. stolzmanni. In all particulars of structure of feet, ears, and tail this species seems to agree with the type of the genus /. stolzmanni, Thomas, P. Z. S. 1893, p. 339 ; the most conspicuous outward distinction being the difference in the coloration of the tail and feet. I think the make-up of the skin has largely to do with the greater length of head and body in the specimen under consideration, as the size of the feet and measurements of the skull do not bear out the supposition of its being a larger animal. I am unable to throw any light on the cause of the large infraorbital foramen ; but I can say that no muscles pass through it, and that the nerve seemed very small when relaxed after it reached the Museum in a dry state. 3.

Smith in the West-Indian islands of St. Vincent and Grenada and in some of the small islets called the Grenadines, situated between the two larger ones. A few specimens were also obtained from Barbados. Mr. Smith's skill as a collector is well known, and as he spent a considerable time in both St Vincent and Grenada, and visited all parts of each island, we may fairly conclude that the present list embraces the name of nearly every species found in them. The result proves, we think conclusively, that the Butterfly fauna Paoo. ZOOL. Soc.-1896, N o . X X X I I I . 33 |
