SAGARTIDA. 
This family is still in need of a thorough revision, as only a few of its 
members have been thoroughly examined. The best work in this family has 
been done by Dr. Carlgren,* who recognises three sub-families (Sagartine, 
Metridinz, and Phellinz). We admit that the accounts of the following three 
species is very inadequate ; but our material was very limited, and most of the 
members of this group are so very contractile that it is, as a rule, extremely 
difficult to study preserved examples. 
We recognise that our three forms belong to two genera, the first, S. Carlgreni, 
evidently belongs to the Sagartinz and probably to the genus Sagartia. The two 
other species, I, Australie and M. similis, are closely allied to one another; they 
may belong to the Metridinz or to a new sub-family, and we think they should 
be placed in a new genus. 
SAGARTIA (Gosse, 1855). 
Sagartia Carlgreni, n. sp. 
(PL. viz, fig. 13.) 
Form.—Column, elongated and cylindrical, smooth; pedal disc large, flat, 
sinuous margin; oral disc of not much greater diameter than the column. 
Tentacles, numerous, long, thin, subulate, apparently in three cycles. Mouth 
large. 
Colowr.—Column, pedal and oral dise bright deep-orange ; tentacles, opaque. 
white for their proximal third, greenish-grey for their distal two-thirds. 
Dimensions.—Judging from the coloured drawing, the height is about 20 mm., 
with an average diameter of about 10 mm. ‘Tentacles about 10 mm. long. This 
specimen is probably not full-grown. 
Locality.—Port Philip (January, 1892). 
Two specimens were received. We give ourselves the pleasure of associating 
with this species the name of our distinguished Scandinavian colleague. 
Body-wall.—Vhe ectoderm is regular in structure, with a definite cuticle. 
Small oval nematocysts are very abundant in the upper part of the column. 
The basal muscle threads are clearly seen. The ectoderm is much folded in the 
contracted specimen. The mesoglcea in the latter is quite thick, and presents a 
granular appearance owing to the abundance of uniformly small granular cells 
The endoderm is regular and pretty thick, and its muscle is fairly well 
developed.
