ANNELIDA OLIGOCH^TA. 
Lumrrtcina. 
Moyascolcx (Uffrinycns, sp. n., llaird, I c. p. 41. figs. 1 to 4, from a plant- 
stove in the gardens at Plas Machynlleth, in Montgomeryshire, North Wales. 
Baird thinks that there is no sufficient distinction between Schmarda’s genus 
Pcrichceta and Templeton’s Megascolex, and proposes to do away with the 
former. He mentions that Schmarda does not quote the description of 
Templeton’s genus accurately j and we may observe thkt the same mistake 
has been fallen into by Vaillant, who probably simply copied Schmarda (see 
<Zool. Rec.’ 1868, p. 648). 
Claparede & Mecznikow, I, c. p. 191, describe the development of Xwm- 
hricus capitotus, Eabr. 
Lumhricus. Ratzel, 1. c., states that the development of the mouth and the 
primitive streak and the origin of the colossal cells ” is just the same in 
Lumhricus as in Nephelis. 
EnCHYTR.3EINA. 
Pachydrilus krohnii, sp. n., ClaparMe. Described in a footnote in Clapa- 
r^de’s memoir on the minute anatomy of the Earthworm, p. 671, q. v. ; it 
would appear that the structure described as met with in the hypodermis 
of the Earthworm is not peculiar to it among the Oligochfeta, but is also 
met with in this new species of Pachydrilus, which is not marine, but lives 
in the salterns of Kreuznach. 
Naidina. 
Nais serpentina. Lankester, 1. c., calls attention to the development of a 
new segment between the larval fourth and fifth fascicular segments, which 
is provided with fasciculi carrying a special form of genital setje.” 
Ch^togastrina. 
Chcctogaster limncei. Lankester, 1. c., describes at length and figures the 
sexual form of this worm.
