Remarks. — The frequent occurrence of this species in the Indian region suggests 

 the presumption that the Aulophorus oxycephalus of SCHMARDA from Ceylon may 

 be identical with it. It is a fact of no importance that SCHMARDA did not see the 

 gills, for these structures are often contracted so as to be inconspicuous. But in 

 accepting this identity we must regard SCHMARDA' s description as very inaccurate. 

 He speaks only about capilliform dorsal setœ, and in his figure these dorsal setae 

 begin at the second segment. On the other hand I may point out just such an inaccu- 

 racy in vSCHMARDA's description of Aulophorus discocephalus from Jamaica, a 

 species doubtless nearly allied to A. schmarda, MICHIvSN., from Paraguay and doubt- 

 less provided with forked dorsal setse as well as all other species of this genus. If 

 A. tonkinensis should ever be fotmd in Ceylon, the patria of A. oxycephalus, I should 

 propose to unite the former with it. 



About the habits of this worm Dr. N. ANNANDALE gave me the following note : 

 " This worm inhabits a moveable case resembling those of Trichopterous larvae and 

 formed of minute pieces of vegetable débris, sponge gemmules and the like. It moves 

 along fiat horizontal or vertical surfaces in the following manner : It extends the an- 

 terior part of its body out of the tube as far as possible along the surface and applies 

 its anterior sucker [doubtless the protrusible pharynx (MICHAEIySEN)]. It then con- 

 ■ tracts its body, still retaining hold by means of the sucker. Its ventral surface, re- 

 maining in close contact with the object on which it is moving and aided by the chsetae, 

 retains the animal in position while the sucker is released and the anterior extremity 

 again stretched forward. As this process is repeated continually the worm moves 

 forward with a series of jerks. The case remains free, containing the posterior half 

 of the body, which is not so highly extensive as the anterior part. The processes at 

 the tip of the abdomen [i.e., the palps (MICHAELSEN)] protrude from the posterior 

 extremity of the case throughout each forward movement."
