92 IIYDRACARINA 



'riic iiKiIe genital opening is siirroim(U<l l>y two soinilunar, liristlc-bcaring genital valves. 

 The female has no genital plates, but some bristles are inserted in the skin lietween genital 

 opening and epiniera; at the anterior end of the opening tlie l)ristles are crowded, forming a 

 group of 4-5 bristles on each side.

Family PROTZIIDAE 



Subfamily Protziinae 



3. Protziella hutchinsoni gen. et sp. n. 



Generic diagnosis. Skin papillated. Eyes in capsules. Frontal organ lying in a shield, 

 the latter consisting of frontale, prae- and postfrontalia, dorsocentralia 1, and postocularia. 

 Frontal organ rudimentary, but clearly visible and redoubled, divided in two lateral parts, 

 each with a small spot of pigment. Palp chelate. Legs without swimming hairs. Claws 

 simple, as in Partnunia, not split up into a number of teeth. Genital plates present, situated 

 inside the acetabula. 



At present there are four genera known within the family ProtzHdae,^ viz., Protzia, Part- 

 nunia, Calony.v, and Neocalonyx. One of these, Partnunia, has simple, all the others com- 

 posite claws. Protzia differs from Ccdonyx and Neocalonyx by the lack of genital plates. 

 Neocalonyx differs from all other genera in the palpi not being chelate and in tlie skin, tend- 

 ing to a development of chitinous plates. The new genus comes nearest to Partnunia, the 

 claws being simple, but differs remarkably from all genera by the structure of the frontal 

 shield and the fairly well developed frontal organ, which is composed of two distinct parts. 

 In the structure of the skin the new genus somewhat resembles Neocalonyx, a number of 

 small dorsal chitinized plates or punctures being developed. 1 f there is any closer affinity 

 in the genital area it is impossible to say so far, since it is difficult to ascertain the structure of 

 the genital organ in Neocalonyx from Walter's description, for instance, if the genital plates 

 are situated inside or outside the acetabula. 



Description of species. Length of body 983ju. ( 5 ) - 1500iU ( S ). A detailed study of 

 the structure of the skin, the presence and situation of chitinized plates and dermal glands, 

 etc., in the family Protziidac has never been performed. Some years ago, however. I shortly 

 drew attention to the fact that Protzia cxiuiia has the dermal glands and dors.il bristles dis- 

 tributed over the skin quite after the same plan as the Thyasinae, for which I have drawn up 

 a special terminology (Lundblad, 1927, pp. 210 and 221-23). According to this we find on 



' Or five, if also Wandesia Schecht., known hitherto as a nymph only, belongs to the family in question.
