670 MR J. T. CUNNINGHAM AND MR G. A. RAMAGE ON THE 



branchiae, divided into two parts dorsally, entire, without ventral or lateral 

 incisions. Anterior part of the body composed of eight somites. No ventral 

 scutes. Setigerous tubercles beginning from the collar somite, with setae of 

 two forms in the anterior part of the body, the longer form bordered, the apex 

 much attenuated and slightly curved; the shorter form, subspatulate, the apex 

 shortly mucronate, unequally bordered on both sides, one margin having a much 

 broader border than the other; in the posterior part of the body all the 

 capillary setae of the same form, with a narrow border, and the apex long and 

 tapered. Uncinigerous tori beginning from the second setigerous somite with 

 a single row of uncini, in the anterior part of the body, beaked, with a some- 

 what elongated manubrium, and the vertex of the rostrum subserrulate, but 

 in the posterior part of the body they are short and avicular. Branchiae 

 forming a semicircle on each side, connected by membrane for more than half 

 their length ; their apices free, bordered on each side, with no dorsal appendages 

 nor eye spots. Tentacular cirri round, filiform, unequal, many on each side.

On the Rost and North Channel, north of Inchkeith, 1st November 1886 ; 

 also west of Oxcars, November 1884. 



The specific characters as given by Malmgren are as follows : — Body of 

 50 to 80 somites, the breadth equal to a twelfth or eighth part of the length. 

 Collar moderately produced, of equal height on both sides ; anterior margin 

 entire, running down into a vertical sinus, and divided by a deep dorsal furrow, 

 linear and not gaping. Branchiae having their free apex of moderate length, 

 and entirely enclosed in a leaf-like bordering membrane. Colour in spirit 

 entirely white ; branchiae in most living animals intensely purple, especially 

 towards the apex, either all of one colour or spotted with yellowish-white ; in 

 the smaller specimens, the branchiae paler red, spotted with white or pale 

 yellow. It inhabits a tube of yellowish membrane, covered with a coat of sand 

 externally, fixed to stones, or often to Ascidians. Length 15 to 18 mm., breadth 

 17 to 6*5 mm. ; length of branchiae may reach 27 mm. (PI. XLIV. fig. 32).
