So far as I can ascertain the African species which Adansou studied 

 has not been again recognised. Tlie identity of the type is, therefore, 

 obscure.

There occurs in Victoria and South Australia, either a group of 

 indefinite and closely allied species related to Btdli)ius teimistriatus or one 

 very variable species whose limits of aberration are not yet ascertained. 

 Thus Tate writes (Op. cit., p. 212) : — " I have little doubt that JJ. textar- 

 atns, Ik pinictnrutH'i and B. teimistriatus are variants of one species." And 

 Cooke (0[>. cit., p. 136, footnote) suggests a still broader union, connecting 

 B. te.ctiiratiis with B. proteas, Sowerby, B. pyramidatus, Sowerby, B. dispar, 

 Sowerby, B. pectorosa, Conrad, B. hrevicnhnen. Smith, B. ha.dii(, Adams & 

 Angas, and J>. concinna, Adams & Angas. 



These opinions are entitled to serious consideration. 1 have not 

 yet sufficient information either to confirm or to deny them. 



B. TENUISTRIATDS (sensii stricto). It is to be regretted that when 

 revising this group, Mr. E. A. Smith did not supplement with measure- 

 ments and other details the incomplete original description of Sowerby. 

 The type of B. teimistriatus came from the Torrens River, near Adelaide, 

 S. i^ustralia. By means of specimens collected there and determined by 

 Prof. Tate, I am enabled to recognise typical specimens in a lot collected 

 at Overland Corner, Victoria by Mr. F. H. Taylor. One of these hei'e 

 figured (PI. i., figs. 1-2.) is 13 mm. long and 9 min. broad, very thin and 

 transparent. The suture is margined beneath by a narrow pale line 

 followed by a broader dark baud, there is also a broad dark stripe within 

 tlie outer lip. The sculpture consists of exceedingly delicate radial
