1S73. WiLLEMOES SuHM, RuDOLPH VON, borii September 11, 1847, died September 13, 

 1875 (John Murray). 



" Oil a uew genus of Amphipod Crustaceans." (March 6, 1873.) Proceedings 

 of the Royal Society of London. Vol XXI. London, mdccclxxiii. pp. 206-208. 



The now genus Thaumops is thus defiuod : — 



" Cajjut oblonguru, intlatum, oculis maxiniis superiorem capitis partem tegentibus. Segmenta 

 thoracica 6, abdominalia 5. Antennarum in feminis par unum, maxillarum par unum, 

 pedum paria duo minima maxLUaruni locum tenentia. Mandibula? nulla3. Pedes thoracici 

 5, abdominales 3 in quoque latere. Appendices caudales 4. Gangliorum pectoralium 

 paria 5, abdominalium 3." 



The type is given as "Thaumops pellucida, n. sp. Corpus lougitudiue 14 [84] mm., latitudine 

 21 mm., pellucidum." 



The full description, with plates, was afterwards publislied in the Transactions, with, various 

 corrections, but both genus and species were, shortly after their institution, identified by their 

 author with Gu^rin's "Cystisoma Neptunus." The "new family, Thaumopidoe, belonging 

 to the tribe of Ilijperina," which he here jsroposes to establish, was dropped, and a uew 

 family, Cystisomidae, proposed. See Notes on WUlemoes Suhm, 1874, 1875, 1S79.

Bijdrage tot de kenuis van de Crustacea Hedriophthalmata van Nederland en 

 zijne kusten. Groningeu. 1874. 



The introduction contains a short historical review of carcinology, and, among other points, 

 suggests that the Hedriophthalmata, in spite of their comparatively small size, are the 

 highest representatives of their class, on account of their dispensing with the nauplius- 

 and zoea-stages, on account of their including many terrestrial forms, aud on account of 

 their late appearance in the strata of the earth, the Podophthalmata having been met with 

 as early as the carboniferous, the Hedrioj^hthalmata not till the Jurassic period. 



Descriptions are given of several well-known species, with interesting remarks upon them ; the 

 " calceolus " on the antennse of Gammarus pulex is figured and discussed.

This report opens with some occasional remarks on the appendages of the antenna', the eyes, 

 comparative measurements, and classification of Amphipoda. 



Valuable remarks are made on the Lysianassida;, with the species Anonyx larjena, Kr., projjerly 

 Awjuyj; nugax, Phipps ; Anonyx littoral is, Kr.; Anonyx plautus, Kr., for this and the pre- 

 ceding species the genus Anonyx being adopted in preference to Onesimus, Boeck ; the 

 SyrrhoLnse, species Syrrhoii crenulafa, Goes ; the Pardaliscina^, species Pardalisca cuspidata, 

 Kr., which, as well as most of the following, is fully described and strikingly figured ; the 

 Leucothointe, species Uusirus cusjndatus, Kr., Avqihithonotus acideaius, Lepechin, identified 

 with Tritropns lieUeri, Boeck, as well as his Tritropis aculeata ; Tritropis {now Rhachotropis)
