remains similar to Agathis have not been listed. 
One Cedar Lake specimen (USNM #97080) gave a 
spectrum similar to that of Baltic Succinite (Langenheim 
and Beck, 1965). The presence of this spectral type 
might suggest two different botanical sources of the am- 
ber from the Manitoban deposit. 
Baja California Amber 
Buddhue (1935) described ‘‘Bacalite’’ as amber pre- 
sumably from Baja California, Mexico. Since this amber 
cannot be shown to have come from Baja California, 
Langenheim, Buddhue and Jalinek (1965) recognized 
that ‘‘it may have come from any place in the world.”’ 
They mention, however, the particular likelihood of its 
being from the amber deposits of Chiapas, Mexico. 
Hurd, Smith and Durham (1962) reported docu- 
mented occurrences of amber from Baja California, based 
on the discovery by A.C. Allison and F.H. Kelmer. 
Langenheim, Buddhue and Jelinek (1965) further elabo- 
rated on the age and occurrence of this amber. It has 
been observed at three localities between Punta San José 
and Punta Cabras. At each locality, a single nodule of 
amber from 14—2 inches in diameter was collected from 
siltstone or sandstone thought to be latest Campanian or 
sarliest Maestrichtian in age. At Punta Baja, about 10 
miles southwest of KE] Rosario, small fragments of amber 
occur in sandstone with carbonized leaf impressions. 
Metaplefenticiras pacificum Smith occurs in the same bed 
and indicates late Campanian age. Small grains of amber 
and carbonized wood were also reported from a sandstone 
interbedded with a claystone south of the mouth of 
Arroyo Rosario. 
Four spectra were run from a single collection (Uni- 
versity of California, Museum of Paleontology, B-8006) 
from the Punta San José locality. The material generally
