86 MESSRS. MURIE AND MIVART ON THE 
In Cheiromys this double muscle is just as in L. catta, except that the part springing 
from the flexor tendon supplies the whole of the perforated tendon of the third digit. 
LumpricaLes '.—These are four in number, and arise from the tibial side of the deep 
flexor tendons of the four peroneal digits, and are inserted into the tibial side of the 
same digits. 
The so-called lumbricales figured in Cuvier’s ‘ Recueil’ are really part of the flexor 
brevis digitorum, as we have before said. 
The lumbricales are figured in Galago crassicaudatus (PI. I. fig. 3, and Pl. V. fig. 24, 
GS TG EF); 
In Nycticebus tardigradus these are only three in number, none going to the index. 
FLEXOR BREVIS HALLUCIS.—Relatively it is a large muscle, which arises from the meso- 
and ectocuneiform bones. Embracing the long flexor tendon of the hallux, it is 
inserted as usual. 
This is called in Cuvier’s ‘ Myologie’ ‘‘ court abducteur du pouce,” pl. 70. fig. 3, p. 
In Galago crassicaudatus (P1. II. fig. 3, Pl. V. fig. 24, and Pl. VI. fig. 30, £.0.h) and 
both in G@. garnettii and G. allenii it arises from the deep plantar fascia and plantar 
surface of the interossei. Insertion, the outer side and plantar surface of the proximal 
phalanx of the hallux. 
Burmeister? describes this muscle in Tarsivs under the names flexor brevis hallucis 
profundus, his flexor brevis hallucis superficialis being only a portion of our flexor brevis 
digitorum. It arises by two heads, one from the ectocuneiform and the proximal end 
of the first metatarsal, the other head from the meso- and ectocuneiform—and is inserted 
as in L. catta. 
Agpuctor HALLUCIS.—Also a strong muscle, arising from the plantar fascia and 
inserted by a strong tendon into the proximal phalanx of the great toe. 
This is confounded in Cuvier’s ‘ Recueil’ with the plantar part of the flexor brevis, as 
before said when speaking of that muscle, pl. 70. fig. 3 (Lemur varius). 
In the genus Galago the origin is the sesamoid bone at the proximal end of the 
hallux and deep plantar fascia. Insertion, metatarso-phalangeal ligament and plantar 
surface of the proximal phalanx of the hallux. Figured in Galago crassicaudatus 
(Pl. Il. fig. 3, Pl. V. fig. 25, and Pl. VI. fig. 30, Ad.h). 
In Tarsius* it goes from the naviculare to the hallux. 
ADDUCTOR HALLUCIS AND TRANSVERSUS PEDIS*.—In Lemur catta we found but a single 
broad slip representing these muscles. It arises from the third metatarsal bone, and is 
inserted into the proximal phalanx of the pollex.

> Loc, cit. p. 81, tab. 5. fig. 10. no. 44, and also fig. 9. no. 45, the dotted line leading to this last number 
having been by mistake carried on beyond the muscle it ought to indicate (namely, the transversus pedis 
inferior) to the flexor brevis hallucis.
