produced orally. Adoral shields meeting within, somewhat widened 
at the inner end. Oral papillæ small, short, 4—6 to each side. 
The inner ventral plate as broad as the following ones, but some- 
what shorter. Only the two first are in contact; from the fourth they 
are widely separated, the plates being from here nearly rectangular, 
with only a small peak within. The side armplates are slightly 
thickened; they carry 3 short spines, only 1/3 the length of a joint. 
The tentacle scales are 3 at the outer, 2 at the inner side of the 
pore on the first arm joint; already from the 4th joint there is only 
one small scale. 
Fig. 6. Ophiotjalfa vivipara; oral side. 78/3. 
The species is viviparous; in fig. 4 two young ones are seen 
to protrude with their arms through the bursal slits. 
This species must evidently form the type of a new genus. 
In general it resembles Ophioglypha, but through the complete 
absence of combs it differs so essentially from this genus that I 
think it unjustifiable to include it therein and thus still add åa 
new form to the rather chaotic assemblance of species referred to 
it. That the genus Ophioglypha must be subdivided, is evident 
enough. Perhaps some species will have to be referred to the new 
genus established here. But this is not the place to enter on the 
difficult problem of subdividing the genus Ophioglypha. — 4150 
to Ophiozona this new form bears a general resemblance, but if
