ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 557 



Revision of Distomid Family Hemiuridse.* — A. Looss gives a 

 preliminary communication on this subject, in which he outlines the 

 characteristics of the family and its genera. He limits the family to 

 the typical Hemiuridte — i.e. those forms which possess a retractile hind 

 body, or at least, which agree fully with these in the main features of 

 their organisation. In this arrangement, the genera Derogenes, Acca- 

 ccelium, EurycoeUum, etc., admittedly closely related, are excluded, 

 though included in Luhe's definition of the group. 



Bilharzia of Cattle in Sumatra.f — A. Vryburg states that in the 

 blood of the liver of cattle in Deli-Sumatra, bilharzia are often to be 

 found. During Hfe there are no indications of illness and they are hence 

 found only accidentally. They occur also, usually few in numbers, in 

 the blood of the mesenterial vessels. In a zebu killed on account of old 

 age and blindness, 150 were found in the hver blood and 13 in the 

 vessels of the gut. From a consideration of the size and appearance of 

 the males and of the eggs, the species is probably Schistosomuin spindalis 

 Montgomery. The Sumatra females are smaller, ])ut the two types are 

 probably the same. 



New Turbellarian from Hawaii. | — Harold Heath describes Plano- 

 cera hawaiiensis sp. u., from the Auau Channel, Hawaii, where the depth is 

 28-43 fathoms. The largest specimen is o9 mm. long and 38 mm. wide. 

 The species is colourless, or with faint black blotches and streaks on the 

 dorsal surface. There are five lateral and one anterior intestinal branches 

 which anastomose frequently. The penis carries three kinds of hooks 

 or spines, some of large size. These appear to be cuticularised papillse 

 — not, as Lang maintains for P. graffii, modified epithelial cells. 



Incertae Sedis. 



Antarctic Brachiopods.§ — Edgar A. Smith describes two species 

 collected by the ' Discovery,' Magellania fragiUs and M. sulcata, both 

 apparently new. The former is very closely related to M. Jcerguelenensis 

 ■of Davidson and to the Patagonian M. venosa of Solander ; the latter 

 is remarkable on account of the concentric sulcations and the coarse 

 perforations of the shell. The author does not know of any recent 

 form that exhibits sulci or marked lines of growth of this kind, but 

 among fossil forms a similar kind of surface ornamentation is met with 

 in Terehratula sulcifera Morris of the lower chalk. 



New Cephalodiscus.|| — W. G. Eidewood gives an account of a new 

 species of Cephalodiscus {C. hodgsoni) and of C. nigrescens Lankester, 

 both obtained by the ' Discovery.' In the former the tubarium is an 

 irregularly branching tube, with lumen varying in size, but with inner 

 surface smooth, and not with partial septa and trabecular ; the ostia are 

 oval, about 3*3 by 2*3 mm., with four or five long radiating spines, 

 simple or forked ; the polypides are colourless, or nearly so, with no
