in Cebus capueinus and on a child’s skull. Meanwhile such little 
pieces of bone occur very seldom in the sut. coronalis. Here we find 
the abnormal suture developed only on the right side, nothing is to 
"be seen on the left side. As the picture shows the sut. lambda is not 
reached by the sut. par. This skull still has another peculiarıty: 
in the Bregma, the place of the embryonal large fontanel we find a 
narrow but distinet os bregmaticum of oblong shape. HRDLICKA 
too found in Macacus rhesus a fine example of the coinciding of an 
os bregmaticum with the sut. par. He gives a good picture of it; the 
skull seen from above. Among the monkeys, especially in the genus 
Cebus this superfluous os bregmaticum occurs rather often as was 
found by Ficausr in 1900. In 1872 
W. Gruser has published a detailed 
communication about this piece of bone, 
and treated its occurrence in man and 
the other mammals. 
In 1900 HrpuıckA (22) has described 
a skull of Anthropopithecus troglodytus 
with a right and left sut. par., from which 
he has given a picture, seen from above. 
As by far the most pictures of the sut. 
par. are seen in profile, it seemed desirable 
to me to represent his picture here, see 
fig. 4. This case of HrDLIEKA’s is there- 
fore also important because it shows defor- 
mations in the sutures, also in the sut. par., 
so that these sutures do not continue, a thing which I also described 
for Papio maimon (see above). Further we also see some islets of 
bone on the right side of fig. 4, which I saw too in the same skull. 
Perhaps HrpricKa’s case shows a branching of the sut. par. dextra 
with the sut. cor., through which his case is again a little more like 
mine of Papio maimon. In fig. 5 I have represented another of 
HrpLıcka’s (8) pictures. However the picture is not directly taken 
from the original, but rather copied from the author’s photo, which 
unfortunately has not been very successful; because it is important 
to possess a rather more distinct picture of this very case. For it is 
the only skull of a specimen of the carnivora (Felis pardalis) which 
has been represented with a well developed sutura parietalis. The 
sharp bend in the sut. front. where it meets the sut. par. is very beauti-
