NOVITATES ZOOLOGICAE XXII, 1915. 407 



the Johnsou-Green expedition. The rest were got by the Webster Harris, Leland 

 Stanford, and Captain Noyes second e.Kpeditiou, and by R. H. Beck. Three SS 

 and one ? are mounted on plaster caraj)aces, and the skeletons mounted complete. 

 There are fifty-eight specimens of this race in the Tring Museum. 



Testudo species ? 

 Nos. 91 and 138 are two saddle-backed tortoises of uncertain origin, though 

 both collected by R. H. Beck. No. 138 is indistinguishable from ephippium, and 

 was got in the first half of 1902 and is labelled in Beck's handwriting "South 

 Albemarle."' No. 91 is a saddle-backed tortoise with strongly everted marginals ; 

 it was collected by R. H. Beck, and labelled bj' him " Indefatigable Island. 

 Feb. 16th, 1901." It has a very depressed carapace and much resembles Testudo 

 chathamensis. 



Testudo wallacei Rothsch. 

 (Plates XXXI., xxxii.) 



Testudo xoallacei Rothschild, Noik Zool. ix. p. G19 (1902.) (Type Distington Museum. 

 Locality ?) 



The type specimen consists of a complete carapace with scutes, and was 

 purchased when Mr. Wallace's museum at Distington, Camberland, was dispersed, 

 together with a small ? ? Testudo chathamensis, two very small Testudo nigrita, 

 a specimen of the extinct Nestor productus, the also extinct Carpophaga spadicea, 

 and other rarities. This carapace was bought by Mr. Wallace at the sale of the 

 famous Bullock Museum. The scutes are absolutely smooth, with no trace of 

 striation, and the shape is much more oblong than any specimen I have yet seen 

 of Galapagos tortoises. There is a specimen in San Francisco obtained on Jervis 

 Island by Beck and Slevin which Dr. Van Denburgh refers to this species. Until 

 the cast of this Jervis S is ready for comparison, I feel unwilling to express a 

 definite opinion ; but from the monograph it is clear that while being larger (more 

 than four inches longer in a straight line), this Jervis Island specimen has the 

 scutes strongly and deeply striated. 



Testudo nigrita Dam. & Bibr. 



Testudo nigrita Dameril & Bibron, Erpet. Gener. ii. p. 80 (1835). (Type Huiiterian Museum. 



Locality ?). 

 Testudo porteri Kothsohild, Nov. Zool. x. p. 119 (1903) (Indefatigable Island). 



Dr. Van Denburgh (of. Proc. Cat. Acad. Sci. ser. 4, vol. ii, pt. i. pp. 249-51) 

 gives reasons — and good reasons — for making use of my name of porteri for the 

 Indefatigable tortoise, and only quoting nigrita under it with a query. 



I, however, in this case, am in favour of using the older name, as I think it 

 can be proved to belong to this race. 



The type of Dnmeril & Bibron's description is the specimen in the Hunterian 

 Museum. This consists of a complete carapace with scntes. I have carefnlly 

 compared it with the Indefatigable Tortoise brought home by Mr. Gerrard from 

 San Francisco, and, although the latter is slightly larger, the two agree in every 

 character most exactly. 



I therefore reluctantly feel obliged to sink my own name porteri as a synonym 

 and reinstate nigrita Dum. & Bibr. for the tortoise of Indefatigable Island. The 

 type of nigrita is certainly a ?. Nos. 103 and 104 were bought in 1833 from a 

 whaling boat in Callao Bay by Mr. AVallace, of Distington, at the dispersal of 

 whose museum I obtained them.
