Figure 'k . Two structural types of the m. anconeus in lizards. 



A - Lacerta lepida has only one long "scapular" head originating from lig. 

 axillaris and lig. scapulo -humeral is lateralis; this structural type of m. 

 anconeus is noted in all Scinco-gekkonomorpha. B - Phrynocephalus mystaceus : 

 primitive single long head of m. anconeus divided into two - the coracoid 

 originating from lig. axillaris and the scapular which at its origin is com- 

 pletely separate from lig. axillaris and lig. scapulo-humeralis lateralis. 

 There are two long heads of m. anconeus in all representatives of the Iguano- 

 morphic line of evolution of lizards. St - sternum, a - long head of m. 

 anconeus in Scincogekkonomorpha, ac - m. anconeus, caput coracoideum, acsc - 

 m. anconeus, caput scapularis - ahl - m. anconeus, caput humerale laterale; 

 ahm - m. anconeus, caput humerale mediale; ax - lig. axillaris, cbl - m. 

 coraco-brachialis longus , ccor - coracoid part of coracoid head of m. 

 subcoracoscapularis , m - latissimus dorsi, scsb - spacular head, m. -" 

 subcoracoscapularis ; scor - spacular part of coracoid head, m. subcoraco- 

 scapularis, scs - m. stemo-costoscapularis , shl - lig. sterno-humeralis 

 lateralis, ssi - lig. sternoscapularis internum, stci - mm. sterno-coracoidei 

 inertni . Other symbols explained in Figure 1. 



Figure 5- Three basic structural types of the m. supracoracoideus 



A - Lacerta lepida, B - Agama caucasica, C - Phrynocephalus mystaceus; sac 

 m. supracoracoideus accessorius , sc - m. supracoracoideus.
