98 EDENTATA. 



The following specimens are of larger size than the preceding, hut arc 

 provisionally regarded as belonging to the male of the same 

 species ; tJiey are all from the caverns of Minas Geraes, Brazil, 

 and belong to the Claussen Collection. Purchased, 1845. 



18627. The left scapula. This bone differs from the scapula of 

 S. leptocephalum by its superior size and greater relative 

 width, as well as by the greater stoutness of the acromio- 

 coracoidal bar and the smaller size of the foramen. In 

 relative width it agrees with the type scapula of the 

 present species, but differs by the more convex anterior 

 border — a character which may be only sexual. 



18627 a. The right scapula, belonging to the same individual as the 

 preceding. 



18649 C. The left ulna, wanting the distal epiphysis. 



18652 a. The left ulna. This bone is relatively longer than the ulna 

 of the type species. 



18620 a^*. The distal half of a right ulna, perhaps belonging to this 

 form. The distal extremity differs slightly from that of 

 No. 18652 «. 



18620 a^'. The proximal half of the left radius. 



18979. The proximal half of the right radius. 



18620. The right femur. This bone is longer than the type femur 

 of S. leptocephalum, its extreme length being 0,448 and 

 its distal width 0,216. The concavity on the anterior 

 border is relatively longer than in the type species. 



18932. The right femur. 



18932 a. A crushed specimen of the left femur. 



18652 a^^ The right patella. This specimen differs from the cor- 

 responding bone of S. leptocephalum (No. 37473) by its 

 greater length and flatness, as well as by the smaller pro- 

 portionate size of the articular facette. It agrees precisely 

 with the corresponding bone of the hind limb of the present 

 form, figured by Burmeister in the ' Monatsb. k. preuss. 

 Ak. Wiss.' 1881, plate facing p. 380, fig. 3, under the name 

 of S. leptocephalum. 



18620 a^ The left fibula.
