OSTEOLOGY. 39 
The pelvic girdle (Plate 8, figs. 1, 2) is much like that of Erinaceus in its 
proportions. The pubis is well developed, with a lateral crest for the attach- 
ment of muscles, and quite without the inward arching of the anterior rim so 
peculiarly developed in Gymnura. The symphysis is about 4 mm. long yet 
firm, as in Erinaceus. In Gymnura it is incomplete. The obturator foramen is 
large and subquadrate in outline. The ischial tuberosities are about as far 
apart as are those of the ilia. In absolute size the pelvis of Solenodon paradoxus 
is practically identical with that of S. cubanus. Leche (:07, p. 83, text fig. 77 
has given a figure and description of what he believed to be ‘‘das bisher unbe- 
kannte Becken von Sol. paradorus,”’ but there can be no doubt that the bones 
figured (a pelvis, with sacral and four caudal vertebrae) are not those of Soleno- 
don at all. The figures represent a pelvis larger than that of this genus, with a 
long symphysis pubis, oval obturator foramen, evenly rounded ischia, and caudal 
vertebrae of a totally different character from those found in Solenodon. Doubt- 
less the mistake arose through some transposition of labels, for Leche himself 
remarks upon the astonishing characters that the specimen presents, quite 
different from those of all other “‘Insectivora lipotyphla.”’ 
The scapula (Plate 8, figs. 5, 7, 8) is subtriangular in outline, with a greater 
relative development of the coracoid margin than in Erinaceus. The scapula 
spine is broad and shelf-like but the acromion and metacromion are shorter 
than in Erinaceus and Gymnura, and in this respect resemble these processes in 
Centetes. 
The humerus (Plate 8, figs. 9-11) is short and is remarkable for its great 
expansion distally, on each side of the articulation. The epitrochlear foramen is 
present as in Gymnura, Centetes, and Ericulus. This foramen is absent in 
Erinaceus. In the specimen of Gymnura examined, the olecranal fossa is per- 
forate, but no such perforation was found in Solenodon, Ericulus, or Erinaceus, 
and it apparently does not exist in Centetes. The extreme length of the humerus 
is 49 mm. or about 5 mm. longer than that of S. cubanus; its least breadth is 
5mm. at about the commencement of the distal third of its length. The great- 
est distal expansion is 18.5 mm., of which the articulating surface occupies 7 mm. 
The radius and ulna (Plate 8, fig. 15) are separate and practically as in the 
Cuban Solenodon. The former is narrow proximally with a distinct neck about 
5 mm. from the articulation. Distally it is expanded and articulates with the 
radiale and the intermedium of the carpus. Its ectal face has a shallow longi- 
tudinal groove along the distal three fourths. Its extreme length is 41.5 mm., 
or about 5 mm. greater than the measurement of the same bone in Peters’s
