Baird's Description. 



Colour pale-brown. 



Body cylindrical, 

 narrowed posteri- 

 orly, and ending 

 in a pyriform 

 swelling. 



Cylindrical portion 

 of the body smooth, 

 faintly reticulated 

 anteriorly, but 

 only transversely 

 striated posteri- 

 orly ; theposterior 

 pyriform portion 

 rougher, especially 

 the caudal apex.j 



Proboscis short, 

 roughened, thin- 

 ner than the 

 body.t 



Length, Oin.; length 

 of proboscis, |in. ; 

 breadth of body 

 anteriorly, 0-4in. ; 

 breadth of pro- 

 boscis, 0-25 in. 



Colour white shin- 

 ing-bronze.* 



Body cylindrical, 

 slender anteriorly, 

 posteriorly thicker, 

 fusiform, reticu- 

 lated. 



In the anterior por- 

 tion corrugated, 

 then smoother and 

 miyiutely granu- 

 lated; caudal apex 

 oval, smooth, shin- 

 ing. \ 



Proboscis short, 

 smooth, the ante- 

 rior portion thicker 

 than the body.f 



Length, G^in.; length 

 of proboscis, 6 lines 

 = ^ in. ; breadth, 

 anterior end of 

 body, IJ lines = 

 0-12 in. ; breadth, 

 posterior body, 4 

 lines = 0-3in. ; 

 proboscis, 2 lines 

 = OlGin. 



The general colour is white, 

 except towards the caudal 

 extremity, where it is very 

 shining, with an iridescent 

 metallic lustre. 



The upper extremity is nar- 

 row, the body gradually en- 

 larging in size as it descends, 

 so that at the caudal ex- 

 tremity it is three times as 

 large as anteriorly, and is 

 of a fusiform conoidal form, 

 the warty tubercles at the 

 same time being larger there 

 than elsewhere. Scattered 

 over the surface we see a 

 good many small ivarty- 

 looking tubercles, j 



The body is slender, ringed, 

 the rings or annulations 

 being very close together, 

 small and finely but dis- 

 tinctly reticulated across. 

 The upper extremity is 

 strongly corrugately reti- 

 culate, the middle portion 

 less distinctly so, and tbe 

 caudal almost synootJi.j 



The proboscis is smooth-look- 

 ing, but when examined 

 with a glass we see it 

 ringed or annulated or 

 finely reticulated. Ttie 

 proboscis in this species is 

 much J thicker than the 

 upper or anterior part of 

 tlie body.

; His measurements do not bIjow any excessive difference, there being a dif- 

 ference of only J lino. Baird states that the " oral cirri are not visible," so the 

 proboscis was not fully everted.
