Atkinson (J. A. S. B. Ivii, p. 336) states that he has pro- 

 cured several specimens of these tubes (sp. ?) on the common 

 Jujube {Ziz]ii)hus) in Calcutta. These were serpuliform and re-

 foot, too, was ciu'ved over to embrace the twig on which they 

 rested, and the length varied from halt to two-thirds of an inch.

In the British Museum collection are two specimens in bad 

 condition and labelled " India " which seem to agree fairly well 

 with the above description ; otherwise the species is unknown 

 to me.
