SPECIMENS OF GENERAL ZOOLOGICAL INTEREST. 5 



described by Schneider* in 1869, and whose adult form is not 

 yet definitely determined. 



Phoronidea. — Actinotrocha occurred frequently in the surface 

 net during both August and September. On 16th August, in a 

 flat calm, several specimens were got in the tow-net in the act 

 of metamorphosing. On 10th August two young but completely 

 metamorphosed specimens of Phoronis, each contained in a 

 membranous tube, with sand grains attached to its surface, 

 were obtained in the surface net. As the specimens were 

 entangled in small masses of an Ectocarpus-like Alga, their 

 occurrence at the surface was doubtless accidental. Although 

 in habit these young specimens, with their free membranous 

 tubes with adherent sand grains, agree with the Mediterranean 

 P. psammophila rather than with P. hippocrepia, it would be 

 rash to assert definitely that they do not belong to the latter 

 species. 



Tornaria appeared only once in the surface net — on 10th 

 August. 



Tunicata. — The surface waters were frequently swarming with 

 Appendicularians, Although the individuals varied greatly ac- 

 cording to state of maturity or degeneration, all the specimens 

 carefully examined appeared to be the common Oikopleura 

 dioica, Fol.

The following interesting zoological specimens have recently come 

 into my hands, and are destined to be placed in the zoological 

 collection of the University of Glasgow : — 



1. Megaptera longimana, Gray. — The first specimen is a 

 foetus — apparently the smallest so far recorded — of the Humpback 



* Arch. mikr. Anat. Bd. V. The larva in question is here mentioned as 

 " Zweite Species."
