ENDEAVOUR SC'IEMTIFIC RESULTS. 



I may remark that the distinction of the genus or sub- 

 genus Protulopsis rests on a very uncertain feature. St. 

 Joseph^ separates it from Protula owing to the difference in 

 the form of the abdominal bristles, which in the older genus 

 are " sickle shaped," whereas in the new sub-genus they are 

 less curved ; at the same time he points out in a note on p. 338 

 in referring to Filograna, that in the case of these dehcate 

 chaetse immersion in alcohol for some time tends to alter the 

 curvature, to diminish it, so that a sickle form may straighten 

 out, and it is easy then to confuse the chaetse. However, I 

 have retained the name as Willey's species is easily dis- 

 tinguished.
