AD 
HrpuıörA (3) found this superfluous suture in monkeys, it was 24 
times with Macacus rhesus! 
In 1911 Mawnnu (18) gives another case, observed in a child. 
To my regret I have not been able to get this article, no more than 
many other Italian articles about this subject. 
The two last articles which were both published in 1912, are from 
ADALBERT ScHtck (19) and myself (20). As far as my article is 
concerned (the sutura parietalis in Mus decumanus var. albus), I can 
refer to the Anat. Anz. No. 12, Vol. 41, page 347. ScHück’s commu- 
nication gives me occasion for a few remarks. ScHück speaks about 
a sutura intraparietalis. This name has not yet been used by any- 
body else as far as I know, and RANKE, SCHWALBE, FRASSETTO and 
others have always used the old name: sutura parietalis, introduced 
by Hyrrt in 1871. As this name cannot give rise to any confusion 
I prefer to go on using it and not to take ScHück’s new name. 
The cases which he describes are about human skulls, but I do 
not think that we always find a superfluous suture where the author 
mentions it. It seems to me that in fig. 6 e. g. we find a “Randspalte’’, 
and not a suture. SCHWALBE (2) has already said in 1903 (p 421), 
that “Randspalten’’ have already oftener been taken for sutures. 
Ranke (1) and HrpLıcka (3) too have the same opinion and the first 
says on p. 65: „Unter diesen, mit der dicentrischen Anlage des 
Scheitelbeins nicht im Zusammenhang stehenden Randspalten 
RENNER, 3 “ So the ,,Randspalten“ have nothing to do with sutures, 
here the sutura parietalis and have to be explained as accidental 
formations. It is therefore very desirable to judge the superfluous 
sutures with caution. 
With the description of a few new cases of the sut. par. I begin 
with the skull of Cercopithecus sabaeus, see fig. 1. 
This skull is in the Museum of the Zootomical Laboratory of 
Leiden, Holland. The occipital bone and the left parietale are wanting. 
Further the skull is complete. On the frontal bone was written: 
Simia sabaeus; the number is 613 Br. Catalogue %, where the 
object was inscribed as: Cercopithecus sabaeus. In the sut. coronalis 
are two Oss. Wormiana between which the sut. par. begins, (see 
fig. 1) which runs about parallel with the sutura squamosa, and ex- 
tends over the greater part of the os parietale. The length of the sut. 
par. is about 80 m. M. Though this superfluous suture is distinctly 
to be seen on the outside of the skull, nothing can be discovered on
