/ 



Class POLYZOA J. V. Thompson, 1830. 

 = BRYOZOA Ehrenberg, 1831. 



Sub-Class I. ENTOPROCTA 1 ) Nitsche. 

 1869, Zeitschr. wiss. Zool., XX, p. 596. 



Fam. Loxosomatidae 2 ) Hincks. 



Loxosomidae Hincks. 



18S0, "Hist. Brit. Mar. Pol.", p. 571. 



I have indicated above my reasons for believing that the species of this Family here 

 recorded form but a small proportion of those that really occur in Malay waters. The specimens 

 found have been discovered, without exception, accidentally, in the course of the examination 

 of some other species. The Family is obviously abundantly represented in the Indo-Malay Archi- 

 pelago ; and it cannot be doubted that a more systematic search would result in the discovery of 

 other species, particularly if attention were paid to Sponges, Polychaets, Gephyrea and Tunicates. 



I am acquainted with but few references to the Loxosomatidae outside the Atlantic, 

 Mediterranean and Arctic areas; and it may be worth while to mention the cases in question. 

 In a paper on the Hydrozoa and Polyzoa of the China Sea, Kirkpatrick 8 ) has recorded L. 

 crassicaudq.} from the Tizard Bank, 27 fathoms. After examining the original material (Brit. 

 Mus., 89. 8. 21. 71.) I am unable to refer any of the 'Siboga' specimens to the same species; 

 and the condition of Mr Kirkpatrick's specimens does not justify me in expressing an opinion 

 with regard to the correctness of his determination. Whitelegge 4 ) has recorded Loxosoma sp. 

 from Phascolosoma australis (sic). Haswell b ) has mentioned an undetermined Loxosoma which 

 he found on the large chaetae of Coppingcria longisctosa at Port Molle, Oueensland. In his 



1) By many writers tlie name ENDOPROCTA is employed. I know of no reason for departing from the form originally 

 introduced by Nitsche. 



2) It was recognized by KowalewsKY (1S66. "Beitr. Anat. u. Entw. Loxosoma neapolitanum" ', Mem. Acad. Imp. St Pétersbourg, 

 7; X, N° 2), that Loxosoma must lic regarded as the representative of a new Family at least.
