458 THE ZOOLOGIST. 



Mesenchytraus setosus was adult, three specimens being found ; 

 while only two were discovered of M. oligosetosus sp. nov. The 

 Pachydrilids were Marionina crassa (?) represented by eight 

 specimens, and one or two other species not yet diagnosed. 

 Four species of Henlea totalled twenty specimens, there being 

 one to credit to H. insula sp. nov., two to H. parva (?), four to 

 H. hibernica, and thirteen to H. rhatica. Similarly the four 

 species of Enchytraus were represented by thirty-four specimens. 

 Of these E. nigrinus had one, E. buchholzi one, E. minimus six, 

 and E. albidus twenty-six. 



The Fridericias are everywhere in Britain the dominant 

 genus of Enchytraeid. As already stated, the number of species 

 collected in Jersey by Mr. Hillman reached sixteen or more. 

 Of these F. helvetica, F. galba and F. bretscheri, were represented 

 by one apiece ; F. ratzeli and F. leydigi by two each ; F. 

 michalseni and F. glandifera by three ; F. connata by four ; 

 F. polychata and F. ulmicola each by eight; F. bulbosa and 

 F. perrieri by eleven. 



The Lumbricida were well represented, Allurus and the 

 Brandling (Eisenia fcetida) being by far the most numerous. 



Curious Lacuna. — Not a single specimen of any of the 

 genera belonging to the .Eolosomatlda, Naidida or Tubijicida 

 was to be found, and only one specimen representing the family 

 Lumbriculida. This seemed so anomalous that I wrote to 

 Mr. Hillman expressing my surprise. A quotation from his 

 reply may throw some light on the matter. It may be 

 premised that when the consignment reached me it was 

 accompanied by a note saying that the water containing weeds 

 and algae had gone putrid. " The absence of freshwater worms 

 is remarkable, and yet cannot be attributed to the loss of the 

 bottle of water ; because if they had been present in the water, 

 the wet moss and algae would surely have contained them also. 

 I particularly regret the loss of the water, because I had the 

 peculiar conditions of Jersey in view when I got it. There are 

 not six ponds in the whole island, I am told. All the streams 

 are, of course, spring water, plus surface oozings, and the 

 springs must surely be fed by Continental sources ? They run 

 directly into the sea down valleys more or less straight. It is 

 quite possible what ponds there are may be seasonal, but the
