HyYLoBaTES LAR redescribed as H. entelloides. (Yellowish 
white variety).

In this work the following species are recorded: H. LEuciscus, 
wrongly attributed to Schreber; H. acitis; H. miilleri = H. con- 
COLOR; H. raffiesi = H. acitis; H. rar; H. Hootock; H. en- 
telloides = H. tar; and H. syNDACTYLUS = SYMPHALANGUS 
SYNDACTYLUS.

HyYLOBATES FUNEREUS first described.

rales. | 
A synopsis of the species of HytosaTes is here given. An 
important character is considered to be the presence or absence 
of a tubercle on the clavicle, and species recognized accordingly. 
This tubercle, however, indicates a more or less powerful 
attachment for the muscle, and is not a structural character 
nor one bestowing specific value, but is the result of great 
activity or effort on the part of the individual. The species 
recognized are H. Leuciscus; H. miilleri = H. concotor; H. 
HOOLOCK; H. entelloides = H. tar; H. Lar; H. acitis; H. 
ratiest = H. AGILIs.

HYyLoBATES PILEATUS first described. 
Reichenbach, Die Vollstandigste Naturgeschichte der Affen. 
The genus of HyLopaTes in this work is divided into two sub- 
genera A. Siamanga with S. syNDAcTyLus; and B. HyLoBaTes 
with H. rar; H. Hoorock; H. rafflest = H. aciutis; H. LeEvu- 
CoGENYS; H. albimanus = H. var; H. miilleri = H. coNcOLoR; 
H. aciuis; H. entelloides = H. acivis; H. choromandus = H. 
HOOLOCK ; H. FUNEREUS; H. LEeuciscus; H. PILEATUS.

HyLoBaTES NASUTUS renamed H. pileatus.

in Collection of the British Museum. 
In this list the species of HyLopaTeEs are divided into two 
groups: I. Hands and feet white; nose rather elongate; and 
II. Hands and feet like the rest of body. In the first of these 
are placed, H. Lar; and H. piteatus; and in the second, H.
