smallest. It is satisFactory to find that the same conclusions were 

 arrived at by one of the authors of thin paper in a former commu- 

 nication, founded on the studj^ of a smaller number of animals 

 (XLV.). Among the Felidfe F. leo and F. catus CXLV.) have the 

 normal arrangemr'nt, though Mivart (1.) makes no mention of an 

 adductor iudicis in the former animal. In the Viverridje, Cryjtto- 

 irrocta (lOj, V. civetta (12), Genetta (18), Paradoxurus (19, 20), 

 Herpesies nepalrjisis (23), and H. r/riseas (24) were normal. Pro- 

 teles (2.5) had only an adductor to the index and minimus. Among 

 the Hysenidse, H. crocuta (29) had addut-tors to the middle and 

 little fingers, while B. striata (26, 28) had them to the index and 

 minimus. Among the Cauidae, the muscles are normal in C.famili- 

 aris (31, 39, XLV.), but the adductor poUicis is rudimentary and 

 is, according to Meckel (XXXIX.), merely aponeurotic (see fig. 11, 

 p. 406). C. dinrfo (XLYI.) agrees with the other Dogs recorded, 

 but in C. aureus (XLV.) adductors of the pollex, annularis, and 

 minimus were found. Among the Ursidsethe niuscles were normal 

 in U. maritimus (46) and U. ardos (47). In Kelley's specimen of 

 U. maritimus (45) the left-hand was normal, but in the right an 

 adductor annularis was found. In the Procj'onidae, P. lotor (53), 

 P. cancrivorus (57), Nasua (58), and Cercolepti's (61, 62) were normal. 

 In the Musteiidse, M. putorius{()o), Irtont/x lihyca{70), Meles (XLV.), 

 and Lutra (74, XLV.) were normal, though Young' describes an 

 adductor annularis in addition in the last two animals. In Galicfis 

 vittata (63) only adductors to the pollex and minimus were found. 



The Second Layer of Hand-muscles. — Cunningham and Young 

 have described the second layer of the hand as consisting of a 

 series of double-headed short flexors which must not be con- 

 founded with the flexor brevis digitorum manus. These muscles 

 were present in all fixe digits of all the hands we examined. 



Tlie Third Layer of Haud-muscles. — This layer, according to 

 Cunningham, consists of a series of dorsal interosseous muscles 

 whiih abduct the digits, acting from the line of the third meta- 

 carpal. Of these, we saw three in Genttta indr/aris (IS) and 

 Herpestcs ynsnis (24), and Young describes some in Viverra civetta 

 (12). We specially looked for and failed to find them in Cams (31), 

 Jctonyx (70), and Lutra (7i). Iti no other carnivorous animal have 

 we found them nor have we come across any further records of 

 them, but we are quite ready to admit that, unless specially looked 

 for, they are easily missed.
