Turovucu the kindness of Professor Haddon I was given four 
specimens of this species to examine; they were brought by Pro- 
fessor Sollas from Funafuti in 1896. The specimens were pre- 
served in spirit, and the colour, of which no note had been taken, 
was completely lost. 
Form.—The preserved specimens are more or less cylindrical ; 
one is barrel-shaped ; none of them are completely retracted. The 
tentacles are set in three rows on a circular disc; they are simple, 
conical, and blunt at the apex, from which radial longitudinal 
strie run down the wall. The arrangement is entacmzous; the 
number in one specimen is forty-eight, of which the six inner are 
larger than the others. In another specimen there are fifty-four 
tentacles, of which the twelve inner are the largest. The body- 
wall is opaque. The surface of the column is transversely grooved ; 
but there are no warts, tubercles, nor acrorrhagi; the pedal disc is 
well marked in two specimens. The mouth is linear; in two 
specimens the gullet is everted, showing two gonidial grooves. 
In the smallest specimen whitish threads hanging from the mouth 
proved to be acontia. 
Size.—The length of the preserved specimens is 15-23 mm.; 
the average diameter of the column is 8-10 mm. 
Internal Anatomy.—On longitudinal section, the mesoglea of 
_ the lower three-fourths of the body-wall is seen to be much thicker
