Miscellaneous. 469 



Ereb. & Terr. t. This is the first time that the habitat of this species 

 has been recorded. The specimen has a much greener tinge than 

 the two specimens in the British Museum ; but this may arise from 

 its freshness. 



10. Sciurus griseogena, Gray, Ann. & Mag. Nat. Hist. The Con- 

 cordian specimen differs from the others in the Museum from Vene- 

 zuela in having a black streak on the whole length of the back, as 

 \\\ Macroxus medcUinensis, Gray (Ann. & Mag. Nat. Hist.), which we 

 received from Concordia on a former occasion ; but that has a white 

 throat and belly, and is of a smaller size. 



11. Tatusia granadina, Gray, Ann. & Mag. Nat. Hist. 1873. 



12. ChoJcepus Hoffmanni. 



13. Tamandua tetradactyla, var. Icucopygia. 



Additional Note on Tolypeutes conurus. 

 By Dr. J. E. Gray, E.R.S. &c. 



Since I examined this animal, taken out of spirit, and sent 

 a note on it to the ' Annals,' Mr. Edward Gerrard has made 

 a beautiful skeleton of that animal, on which I may further ob- 

 serve :— 



1. The dorsal and the head shield of these animals are much 

 tliicker and harder than the shields of other armadilloes, in this 

 respect showing much affinity to the fossil genera, especially 

 Glifptodon. 



2. The whole internal surface of the dorsal disk is lined with 

 skin, the entire front margin of the front ring being attached to 

 the animal by the skin ; and the central part of the hindei" dorsal 

 disk is attached by cartilage to the central ridge of the pelvis. This 

 cartilage leaves a rough line on the central crest of the pelvis 

 and on the inside of the dorsal disk, showing the extent of its 

 adhesion. 



According to Dr. Burmeister's figure, the pelvis and internal part 

 of the dorsal shield of the Ghjptodon are attached in the same man- 

 ner (see 'Anales del Museo Publico de Buenos Aires,' 1873, ii. 

 part 10, t.). Indeed there seems great analogy in the pelvis and 

 shields between the genera ; but the skulls and teeth are very dif- 

 ferent. A figure of the skeleton and dorsal shield of this animal 

 wiU shortly appear in the ' Hand-list of Mammalia.' 



On the Respiration of the Psammodromi. 



By M. J. JULLIEN. 



The lung of the Psammodromi is traversed internally by very 

 voluminous muscular bundles composed of smooth fibres anastomosing 

 with each other and forming a sort of interior framework, which 

 seems to support the pulmonary tissue properly so called, as in all 

 reptiles.
