^ Colour. Column dirty white and olive-brown in alternate longi- 
’ tudinal lines or dirty white, gray or even pink-coloured. Tentacles 
salmon-pink, sometimes white. Oral disc generally olive-brown. 
Actinopharynx rich pink with darker coloured, red, longitudinal lines

; (Stuekey). The specimens from Kaipara, preserved in formaline, 
were salmon-coloured.

Dimensions of the largest specimen in preserved State; dia- 
; meter of the pedal disc 1,2 cm and of the distal end of the column 
1,4 cm, height of the column 1,? cm. Stuckey’s largest specimen 
was 4 cm high and 2 cm broad. 
Occurrence. Slipper Isl., low water. 20.12.1914. 8 specimens. 
Kaipara. 8.1.1915. 13 specimens. 
Plimmerton (Kirk) and Wellington Harbour (teste Stuckey). 
Manakau Harbour (teste Stuckey and Walton). 
Exterior aspect. The pedal disc is well developed, its dia¬ 
meter often somewhat smaller than the distal part of the body. 
Column smooth, longitudinally sulcated, the furrows corresponding to 
the insertions of the mesenteries. (Textfig. 39). In the middle third 
there are cinelides, propably not more than 2 in 
each longitudinal row. To judge from the sections ^ 
they are probably not numerous. The tentacles are \ 
numerous, in the largest specimen about 192. 
They are in very contracted State almost wart- ' 
like, in half contracted State thin, conical. In pre¬ 
served State the inner tentacles do not reach half 
the diameter of the wide oral disc in length but { ’ - 
are considerably longer than the outer. Somewhat 
more than half the disc is provided with tentacles. Fig. 29. Thoe vagrans. 
Specimen from Slip- 
The actinopharynx is of ordinary length and pro- per isi. Magnif. ii. 
vided with numerous longitudinal furrows and iwo 
ordinarily developed siphonoglyphes with distinet gonidial tubercles 
and rather distinet aboral prolongations. 
Anatomical description. The ectoderm of the column is 
of ordinary height and contains very numerous, longitudinally ex- 
tended gland-cells and numerous nematocysts 12—17 x 2—2,5 //, 
somewhat broader in the basal end, and often a little curved. In 
contracted State of the column the mesogloea is several times 
thicker than the ectoderm, in more expanded State only somewhat
