they do not belong to the same specimen. If the proboscis 

 of A, which seems to have a natural appearance and shape 

 (formol specimen), such as it had when alive, is incomplete at 

 the tip, that of c, which is somewhat distorted (spirit spe- 

 cimen) about the middle, has every appearance of being perfect 

 at its extremity. Consequently I believe that the three frag- 

 ments represent all parts, and show us the full characters of the 

 species so far as is shown by the adult female (see fig. 4). 

 The description is as follows : 



Shape. — The body is elongated and irregularly cylindrical, 

 rather wider anteriorly than posteriorly, with somewhat undu- 

 lating outline along the sides, and with occasional irregular 

 swellings (see fig. 2). At the anterior end it is rounded, and 

 narrows to join the constricted base of the proboscis (fig. 3). 

 The posterior end is evenly rounded. The proboscis springs 

 from the anterior end of the body by a narrow neck, which 

 rapidly widens, while a slit appears in the median ventral line, 

 which widens to form a shallow groove, and then opens out to 

 become the flattened ventral surface of the greater part of the 

 proboscis (fig. 5). Along its whole length the edges of the 

 proboscis are slightly incurved, so that the ventral surface is 

 somewhat concave and the dorsal somewhat convex. The 

 distal portion may be rolled up (see fig. 1), and when unrolled 

 the tip is excavated in the middle, so as to leave two projecting 

 horns at the sides (fig. 3). In transverse section the proboscis 

 is at its base cylindrical, then becomes a deep groove nearly 

 closed in, then an open groove, and finally a nearly flat plate 

 with incurved edges (figs. 1 and 5). 



Surface. — That of the body is tuberculated all over; that 

 of the proboscis is smooth, and when alive of glutinous and 

 slimy appearance. 



Colour. — The body is of a beautiful and nearly uniform 

 apple-green,^ which has the appearance of being quite on the 

 surface of the integument. The proboscis is not so deeply 



• Described by different experienced observers as "chrome" green and 

 "apple" green. Professor Lankester tells me it is exactly the colour of 

 Uamingia.
