to tlie base of the hallux were females (one half of the whole number 

 of subjects of this sex). These comprised two out of the three com- 

 plete specimens. 



28. Extensor longus digitorim pedis.— In one subject (No. 6) the in- 

 nermost tendon of this muscle detached a separate slip to be inserted 

 into the hase of the first phalanx of the second toe, producing an exact 

 analogy to the arrangement in the great toe last described, and which 

 also coexisted in the same subject. It is mentioned by Meckel as ho- 

 mologous to the indicator in man, and as also found in the Pig and Por- 

 cupine (Anat. Comp. vi. pp. 429 & 432). In another (No. 9) a connect- 

 ing slip from the innermost tendon of the long common extensor joined 

 at the base of the metatarsals with that of the extensor ijroprius liallucis. 

 A similar arrangement is said by Meckel to be found in the Kangaroo 

 and in the Euminants. In one (No. 11) the tendons of the second, third, 

 and fourth toes arose by a separate muscular belly from the outer tube- 

 rosity of the tibia and head fibula ; that to the fifth toe coming from the 

 fibres of the peroneus tertius. This is found, according to Meckel, in the 

 IIy£eua, Bear, and other Carnivora, and also in the Kangaroo and some 

 E-odents. In one subject (No. 19) two small slips of tendon, from those 

 of the two outermost toes, were inserted into the shafts of the fourth and 

 fifth metatarsals respectively. This is similar to the arrangement found 

 in the Sloths and Eeptiles. In No. 23 there was a reduplication of the 

 extensor tendon of the little toe. In No. 26 the outermost tendon of the 

 extensor longus was connected with that of the extensor hrevis by a 

 long slip arising from the former above the annular ligament, and join- 

 ing the latter on the dorsum of the foot. In two (Nos. 32 & 33) the 

 tendons of the long extensor were each provided with a separate mus- 

 cular belly. In the former there was also a double tendon to the 

 second toe. 



29. Extensor Irevis digitorim pedis. — In one subject (No. 9) a tendi- 

 nous slip from the second tendon of this muscle joined that of the^r*^ 

 dorsal interosseus ; and another from the tldrd tendon, that of the 

 second dorsal interosseus. In No. 11 this connection existed with the 

 first dorsal interosseus only. This evidence of coDnection between 

 these muscles is interesting in relation to the occasional formation of an 

 extensor hrevis digitorim in the hand, which the author has in former 

 papers explained by posterior displacement and separation of the super- 

 ficial fibres of the dorsetl interossei. In two (Nos. 23 & 26) the 

 tendons to the second toe were doubled. 



30. Flexor longus digitorim and Flexor accessorius . — In one sub- 

 ject (a female) the first tendon of the former muscle was entirely 

 wanting, its place being supplied to the second toe by one from the 

 ilexor hallucis, approaching the formation in some of the Apes. In 

 No. 14 was found a fully developed specizaen of ihe flexor longus ac- 

 cessorius^ arising from the lower third of the hinder surface of the
