P. 4738. Another fine hut contorted specimen 031 in length ; Sahe 
Alma. The slender pointed premaxillse are shown c 
tending forwards beyond the cranial rostrum. The lo "" 
transverse processes of the vertebrae in the hm ® 
abdominal region are shown in impression ; the expa n 
pelvic fin-supports are also preserved. The very narr ^

very clearly produced into the lath-shaped plates o
