brightly coloured. Five species are recorded from the Mediterranean 

 and Atlantic, and immature specimens of one of them (i). grandiflora) 

 have now been found in the Cape Verd Islands. 



Boriopsilla is distinguished by its harder consistency, but especially 

 by having the buccal ganglia close behind the pedal ganglia, and not 

 some distance further back, as in Loridopsis. Bergh thinks this 

 indicates that the conformation of the anterior digestive tract is not 

 really the same in the two genera. Five species have been referred to 

 Doriopsilla.

The notes on the living animals are as follows : — 



" Two specimens found together under a stone, Porto Pray a. 



"Kather narrow in shape. Perfectly soft and smooth, with a 

 conspicuously delicate mantle, fairly wide, always much waved in 

 outline and mobile, translucent and marked by colourless lines 

 radiating from the visceral mass. Ground colour yellow in one 

 specimen, pinkish yellow in another. On the visceral mass this is 

 plentifully besprinkled with dark grey blotches and a few smaller 

 ones of dark red brown. 8 large delicate tripinnate gills tipped with 

 white, as also are the rhinophores. Gills are not covered when 

 retracted, and the edge of the gill-pocket is thick and low. 

 Rhinophore-pocket has raised edge closely fitting to the rhinophore." 



The preserved specimens agree fairly well with Mr. Crossland's 

 notes, but are much contracted and bent, the head- parts, in particular, 

 being greatly distorted. The largest is about 10 mm. long, 9 mm. 

 broad, and 8 mm. high. The skin is smooth, soft, and without a trace 

 of tubercles or prominences. 



The intestines are yellow, and the liver deeply cleft behind. 

 The digestive organs and nervous system as usual in the genus. The 

 oesophagus is considerably twisted, and forms a complete loop. In 

 spite of a careful examination, the usual armature of hooks on the 

 glans penis could not be found with certainty in either specimen, 

 though there seemed to be some minute rods or scales in the lower 

 part of the vas deferens. 



This is probably a young specimen of B. grandiflora, which, when 

 adult, is as much as 9 centimetres long. The best external character 

 of the species is afforded by the lines radiating from the visceral mass 

 to the border, as mentioned by Mr. Crossland. It is possible that the 

 armature of hooks on the glans penis is only developed in the older 

 specimens.
