432 REPORT—1899. 
They therefore trust that the General Committee will sanction the 
payment of a grant of 100/., as in previous years. 
Applications have been received for the coming year from Mr. H. M. 
Kyle, M.A., B.Sc., who proposes to investigate the Anatomy of the 
Pleuronectid, and from Professor W. A. Herdman, F.R.S., to study the 
Compound Ascidians of the Bay of Naples. 
APPENDIX. 
J. Report on the Occupation of the Table on Gephyrea and Allied Worms. 
By H, Lyster Jameson, L.A., PhD. 
During the period for which I had the privilege of occupying the 
Association’s tables at Naples I contined my studies mainly to the Gephyrea 
and other worms. 
I investigated and described in the Naples ‘ Mittheilungen’ an example 
of the worm described by Della Chiaja as Holothuridiwm papillosum. 
Only three examples of this worm have been discovered, all of them in the 
Gulf of Naples. 
In none of these examples was the proboscis preserved, so we have no 
idea of the form of this organ. 
The only extant example bad been, in spirit, for some years, and was 
kindly placed at my disposal by the authorities of the station. I found 
this worm to be an echiuroid Gephyrean, referable to the genus Thalas- 
sema, in which genus it occupies a position not far from 7. diaphenes, 
described by Sluiter from Batavia. These two species agree in their con- 
tinuous longitudinal musculature, simple anal vesicles, and single pair of 
nephridia. Thalassema papillosum may, however, be distinguished by its 
larger size and thicker body wall, as well as by its more highly papillated 
body. Fortunately a sketch of the living animal by Signor Merculiano, 
taken from an example which was subsequently lost, enables us to realise 
the natural colour of this worm. I have had this sketch reproduced in 
my paper. 
I made some researches upon the sipunculoid Gephyrea, having had 
several collections placed in my hands for identification. 
The rich supply of living Sipunculoids, placed at my disposal by 
Dr. Lo Bianco, was of great service to me in this work. 
The results of these investigations are now ready for press. 
Tam at present describing a new giant, Aspidosiphon, sent to me at 
Naples, from Jamaica, by Mr. J. E. Duerden. I believe Phascolosoma 
(Syrinz) granulosum, of McCoy, will prove to be nothing more than a 
large variety of Phymosoma granulatum. I have been unable to find any 
difference between examples of the former from the west coast of Ireland, 
and of the latter from Naples, except in size. 
Other subjects which I investigated, but have not yet sufficiently 
studied to warrant publication, are some questions relating to the peri- 
intestinal sinus in some worms, and alterations in the musculature of the 
intestinal wall which seem to bear a relation to the sinus. 
In conclusion I must offer my hearty thanks to the Committee for 
permitting me to occupy their table, and to the authorities of the station 
for the excellent opportunities and encouragement they gave me.
