New Australian Peripatus.* — E. L. Bouvier describes a new and 

 interesting species of Peripatoides, found at Perth, in Australia. It 

 occupies a place apart, for it shows a strange combination of primitive 

 characters and of characters which have undergone prolonged evolution. 

 It has crural glands in each segment, and sixteen pairs of appendages of 

 archaic shapes. In other ways it is modern : it has no accessory teeth 

 on the external blades of the mandibles, the papillge on the feet are 

 reduced to three, the receptacula seminis are atrophied or absent. 



New Peripatus from the Moluccas.! — F. Muir and J. C. Kershaw 

 describe Peripatus ceramensis sp. n. from Western Ceram. It is the 

 first taken in the Moluccas, and appears from the female characters (for 

 all the sixty-three specimens belonged to this sex) to be very distinct. 

 In the minute size of the eggs and in its mode of development and 

 giving birth (one young one at a time, apparently alternately from each 

 uterus, at intervals of about a couple of weeks) it approaches the 

 Neotropical group, but it is quite distinct in all other characters, such 

 as number of legs, position of vagina, shape of papillae, and number of 

 pads on the legs. In these latter characters it comes nearer to the 

 South African and Australian species, but the bilobate ovarian chamber 

 with the single duct leading from it places it quite apart. It will be of 

 interest to see if Papuan species, when found, will agree with this Ceram 

 form. 



S. Arachnida. 



Spiders of Morocco 4— Eugene Simon reports on a collection of 

 spiders made by M. de la Escalera in Morocco — a region which has not 

 been much explored in this connection. Of the 110 species, 4s occur 

 also in Algeria and S.E. Europe, 20 in Algeria only, 9 in Algeria and 

 and Egypt, 3 in Madeira and the Canaries, 1 (Scytodes major E. S.) in 

 Senegal, 1 {Runciniopsis flavida E. S.) in Tropical Africa, 4 are almost 

 cosmopolitan, and 24 are peculiar to Morocco. 



Harvest Mites on Man.§ — L. Bruyant. finds that the larva of 

 Trombidium gymnopterorum is not really a parasite of man ; it is 

 restricted to Aphides. In many parts of France the larva of Tr. 

 inopinatum occurs on man, as also on mole, water-shrew, cat, hare, 

 partridge, etc. The eggs of Tr. holosericeum developed into larval 

 forms identical with Allotrombidium striaticeps, and this name should 

 now disappear. The larva Tr. holosericeum, occurs also on various 

 Diptera, chickens, ermine, and cat. 



Trombidium and its Allies. ||— P. Verdun points out that Oudemans 

 defines the genus Allotrombidium by a larval character (two cephalo- 

 thoracic knobs), whereas Berlese established it in reference to an
