AN ADDITION TO THE LACERTILIAN FAUNA WAITE. 15 



In both examples which have been figured {G. lorim and G. 

 olivii), the tail has been reproduced, and as usual in such cases 

 the colour-pattern and distinctive scutation of the original member 

 is lost. In our example the tail has not suffered mutation and 

 opportunity is taken to illustrate its character. It is covered 

 with flat juxtaposed scales which are smallest above, increasing 

 in size towards the lower surface ; those bordei-ing the large 

 inferior scutes are quite one-third the width of the scutes. The 

 tubercles upon the upper and lateral aspects of the proximal 

 portion, as far as the hinder edge of the first caudal colour band, 

 are similar to those of the body ; thence the arrangement assumes 

 a distinctive character, the tubercles being confined to the upper 

 surface and disposed in widely spaced transverse rows. Of these 

 the first three ai-e composed each of six 

 tubercles, the two in front having a sup- 

 plementary row of four tubercles an- 

 teriorly ; the next five rows are formed 

 each of four tubercles and the three fol- 

 lowing of two each only, the latter of 

 which is but little differentiated from the 

 ordinary scales. The tubercles occupy 

 the proximal three-sevenths of the tail 

 only. 



As on the body, the markings are in 

 the form of bands though of darker hue, 

 and similarly they do not compass the 

 lower surface. The colour increases in 

 intensity posteriorly and the distal two- 

 fifths is without markings. There are 

 five dark bands on the tail, each twice 

 the width of the interspaces, and on the 

 median line above they are deeply in- 

 cised befoi-e and behind. The accom- 

 panying figure (fig. 2) illustrates the 

 features described. 



The type was, as before stated, 

 taken at Sudest Is. in the Louisiades, 

 and the British Museum possesses 

 examples from Fergusson Is., Wood- 

 lark Is., and British New Guinea. 

 From the latter locality the types 

 of G. Im-icE were obtained, Dr. Wer- 

 ner had three specimens from Dutch New Guinea, and Mr. 

 Garman's G. olivii is recorded from Cooktown. Mr. Woodford
