HAPALIDiE. 
The peculiarities of this family have been mentioned amongst the “Exceptional 
forms.” 
LEMUEOIDEA. 
Spine of scapula ending anteriorly (superiorly) to the middle of the vertebral margin of 
the bone ; suprascapular notch ill defined ; glenoid surface narrow ; clavicle never so much 
as one-fifth of the length of the spine ; humerus never half the length of the same ; 
internal condyle not descending so low as the edge of the inner margin of the trochlea ; 
almost always a supracondyloid foramen * ; supinator ridge almost always large and pro- 
minent ; styloid process of ulna always articulating directly with the cuneiforme ; interme- 
dium generally present, and sometimes interposed between the semilunare and the unci- 
forme ; pollex sometimes reaching beyond the middle of the second phalanx of the index, 
which latter has sometimes only two phalanges ; pollex always with two phalanges ; 
fourth digit of manus almost always f the longest ; ilium never very broad, or its crest 
much arched ; ilio-pectineal line often forming the actual inferior (anterior) margin of 
the ilium ; tuberosities of ischium never flattened beneath ; no subpubic groove ; sciatic 
notches very slightly concave; brim of pelvis never heart-shaped; conjugate diameter 
of pelvis always exceeding the transverse ; a line drawn from the most anterior part of 
the peroneal trochanter to that of the condyles passing quite in front of the shaft of the 
femur ; linea aspera faintly marked or absent ; neck of femur very short ; tibial trochanter 
sometimes larger than the peroneal one ; often a third trochanter ; pit for ligamentum 
teres constant ; rotular surface but little more supported by the peroneal condyle than by 
the tibial condyle ; patella often much elongated ; inner malleolus often much incurved 
and compressed ; fibula not quite always distinct from the tibia ; peroneal malleolus not 
descending below the level of the tibial one ; anterior border of articular surface of tibia 
for astragalus descending a little further than the posterior border ; crest of tibia never 
very sharp ; hallux sometimes equalling three-fourths of the length of the longest digit ; 
tuberosity of calcis always inclined more or less inwards inferiorly; distal articular 
surface of entocuneiforme convex, and mostly saddle-shaped ; hallux always with two 
phalanges ; fourth digit of pes always longest and most projecting ; phalanges of pes 
resembling much those of manus; proximal phalanges sometimes longer than their 
supporting metatarsals. 
LEMUKIDiE. 
Pectoral limb never more than slightly exceeding the length of the spine ; pelvic 
limb, minus the pes, never so long as the spine ; surface of scapula for teres major very 
slightly marked; coracoid process long; radius never half the length of the spine; 
manus never nearly attaining that proportion ; manus never longer than radius ; pollex, 
with its metacarpal, never one-fifth of the length of the spine ; longest digit never attain- 
ing that proportion ; fibula never anchylosed to tibia ; hallux reaching to the middle of 
the second phalanx of the index, or beyond it.
