Show 1888.] ON THE REPRODUCED TAIL OF LIZARDS. 351 LAPHRIS EMARGINATA, Baly. Of this species there are a few examples contained in the present collection, amongst which is a male, which differs considerably in the shape of the antennae from the female sex ; these organs are longer and their intermediate joints are strongly flattened and triangularly dilated, although of the same elongate shape; the broad, black or piceous band of the elytra is occasionally of nearly equal width instead of being deeply emarginate at its middle as in the type. NOTES. In m y catalogue of Japanese Phytophaga (Proc. Zool. Soc. 1885, p. 752) several mistakes and omissions have been made, which I will here rectify, thus :- Lema melanopa is left out, the species is, I believe, found in Japan. Adimonia multicostata, Jac. (p. 755), is identical with Galerucella punctatostriata, Motsch.; the species belongs, however, to Adimonia. Monolepta fiaviventris, Motsch. (p. 755), should have been placed in Malacosoma. According to M . Fairmaire the following species described by him from China (1876) are synonyms :- Paralina impressiuscula, Fairm., = P. fallaciosa, Stal. Lina ignitincta, Fairm., = Galeruca fulminans, Men. Anthraxantha davidis, F., = Mimastra cyanura, Hope. 3. On the Scaling of the Reproduced Tail in Lizards. By Gr. A. BOULENGER. [Eeceived June 5, 1888.] It is a well-known fact that in such Reptiles as have the power of reproducing the tail, the scaling of the renewed portion often differs considerably from that of the normal organ. It is generally held that the difference consists merely in the irregularity of the scaling, or in the absence of certain tubercles or enlarged scutes which are characteristic of the species. Such a view is erroneous. I have convinced myself that, in some cases, the aberrant scaling of the reproduced tail is a reversion to an ancestral form. That a tail with heterogeneous lepidosis may be reproduced as such, is shown bv Hatteria ; the dorsal series of compressed tubercles, so strikingly similar to that of Chelydra, is present on the reproduced portion, which differs only in the scales not being verticillate. That a tail with uniform scaling may be reproduced with diversified scales is exemplified by a large number of Scincoids and some Geckoids, which, having a tail covered with subequal scales, develop on the new portion a ventral, or both a ventral and a dorsal, series of large transverse scutes, such as exist normally in other species of the same or of allied genera. All Lacertidae, Gerrhosauridae, and Scink-like Anguidae, so far as I am aware, reproduce a caudal scaling true to their type. |
